There’s a unique kind of disappointment that every British pool owner knows intimately. You see a sliver of sun in the forecast, you get your hopes up, you prepare the garden furniture, and you excitedly pull back the pool cover… only to be met with water that’s breathtakingly, bone-chillingly cold. That brief window of potential fun slams shut. For years, our family’s above-ground pool was a hostage to the whims of the British summer, seeing use for perhaps a few fleeting weeks in July and August. The dream of a refreshing morning swim or a relaxing evening dip remained just that—a dream. Extending the swimming season felt like an expensive, complicated fantasy, but leaving a significant investment to sit idle for 90% of the year was a source of constant frustration. This is the precise problem that a dedicated, powerful heating unit like the FOKH 5.5Kw Pool Heater aims to solve once and for all.

What to Consider Before Investing in a Pool Heater
A pool heater is more than just an accessory; it’s a key solution for unlocking the full potential of your pool or spa investment. Its primary benefit is obvious but profound: it grants you control over the water temperature, effectively liberating your swimming schedule from the unpredictability of the weather. This means more family time, more exercise, more relaxation, and a significantly better return on the money you’ve already spent on your pool. By maintaining a constant, comfortable temperature, you can start swimming earlier in the spring and continue well into the autumn, transforming your pool from a high-summer novelty into a consistent source of enjoyment and wellness.
The ideal customer for this type of electric resistance heater is someone with a small to medium-sized pool (specifically in the 8 to 13 cubic metre range for this model) who desires consistent, on-demand heating. This user values performance and reliability over the lower running costs of solar alternatives. It’s perfect for owners of larger inflatable pools, rigid above-ground pools, or even small in-ground spas and hot tubs. However, it might not be suitable for those with very large pools, as the 5.5Kw output would be inefficient and struggle to make a meaningful impact. Likewise, if your primary concern is energy consumption and you live in a consistently sunny climate, a solar mat system might be a more appropriate, albeit less powerful, choice. For those looking for a simple, low-power boost for a tiny splash pool, a smaller, plug-in heater could suffice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Before you even think about performance, you must consider the physical footprint. The FOKH 5.5Kw Pool Heater measures approximately 45 x 34.5 x 11 cm. While relatively compact, it still requires a dedicated, level, and weather-protected space in your pump and filter circuit. You must ensure there is adequate ventilation and that it’s accessible for any future maintenance.
- Capacity/Performance: This is the most critical factor. The 5.5Kw (5500 watts) rating indicates its raw heating power. The manufacturer correctly states its suitability for water volumes between 8 and 13 cubic metres (that’s 8,000 to 13,000 litres). Accurately calculating your pool’s volume is non-negotiable. Undersizing the heater will lead to disappointing performance and inefficiency, while significant oversizing is a waste of money. You can see its full specifications and suitability chart online to double-check against your pool size.
- Materials & Durability: A pool heater is constantly exposed to chemically treated water. The FOKH 5.5Kw Pool Heater is constructed from stainless steel, a significant advantage over cheaper, plastic-bodied units. Stainless steel offers superior resistance to corrosion from chlorine and other chemicals, as well as greater structural integrity, promising a much longer operational lifespan.
- Ease of Use & Maintenance: While installation is complex (more on that later), daily operation should be simple. This model features an adjustable thermostat, which is a key feature for “set it and forget it” convenience. Once installed and set to your desired temperature, it will automatically cycle on and off to maintain it. Long-term care involves ensuring your water chemistry is balanced to protect the internal elements and periodically checking for leaks or flow restrictions.
Making the right choice transforms your pool experience.

A Deep Dive into the FOKH 5.5Kw Pool Heater’s Performance
A pool heater’s worth is measured in degrees, comfort, and reliability. It’s one thing to look good on a specification sheet, but another entirely to perform consistently in the unpredictable climate of the UK. We put the FOKH 5.5Kw Pool Heater through its paces, integrating it into a system with a 10,000-litre (10m³) above-ground pool to see if it could truly deliver on its promise of transforming a chilly body of water into a welcoming oasis. Our findings were broken down into three key areas: raw heating power, the critical installation process, and its long-term durability.
Heating Performance in Real-World Conditions
The core function of any heater is, of course, to heat. The 5.5 kilowatt rating is impressive for a unit of this size, and we were eager to see it in action. We started our test on a typical late spring day with an ambient air temperature of 14°C and a starting water temperature of a frigid 16°C. After correctly plumbing the heater into the return line after our sand filter, we switched it on and set the thermostat to a comfortable 28°C. The unit hummed to life quietly, and the indicator light confirmed the heating element was engaged. The principle of a circulating heater is crucial here; it heats the water as it passes through, rather than trying to heat the whole body of water at once like an immersion heater. This method, we found, is exceptionally effective at preventing cold spots and ensuring a uniform temperature throughout the pool.
The results were impressive. Over a 24-hour period, with a solar cover on the pool to minimise heat loss overnight, the heater successfully raised the entire 10,000 litres of water to our target temperature of 28°C. That’s a 12°C rise, a truly transformative difference. Once at temperature, the smart thermostat was the star of the show. It accurately sensed the water temperature and would cycle the heating element on and off as needed to maintain that perfect 28°C. This automatic operation is a huge quality-of-life improvement, removing the need for constant manual intervention. It’s the key feature that delivers the “set and forget” swimming experience every pool owner craves. The reliable thermostatic control is a feature that really sets it apart from more basic models.
Installation and Electrical Requirements: What You Must Know
This is arguably the most important consideration for any potential buyer, and it’s where the FOKH 5.5Kw Pool Heater separates itself from smaller, plug-in heaters. This is not a “plug-and-play” device. The 5.5Kw power draw requires a 220V electrical supply, which means it must be hardwired into your home’s electrical system by a qualified and certified electrician. This is an absolute-must for safety and compliance with building regulations. The electrician will need to run a suitable armoured cable from your consumer unit to the heater’s location, ensuring it is protected by an appropriate circuit breaker and RCD (Residual Current Device). This is an additional cost that must be factored into your budget, but it is non-negotiable for a high-power appliance operating near water.
On the plumbing side, the installation is more straightforward for a competent DIYer. The heater needs to be installed in-line with your existing pipework, specifically on the return line after the filter and before the water re-enters the pool. This ensures that only clean, filtered water passes through the heating element, prolonging its life. The connections are standard sizes, and with the right adaptors for your specific pool plumbing, it integrates cleanly. It’s vital to ensure there are no leaks and that the water flow from your pump meets the heater’s requirements to prevent overheating. While the plumbing is manageable, the electrical work is strictly for the pros. Understanding this upfront is key to a successful and safe installation.
Build Quality and Durability: A Stainless Steel Workhorse
In the harsh environment of a pool’s circulation system, build quality is paramount. This is where the FOKH 5.5Kw Pool Heater genuinely shines. The choice of stainless steel for the entire housing and internal water tank is a significant mark of quality. We’ve seen countless cheaper heaters with plastic housings that become brittle and crack after just a few seasons of exposure to UV rays and temperature fluctuations. The stainless steel construction resists this degradation and, more importantly, stands up to the corrosive effects of pool chemicals like chlorine or the salinity in saltwater systems.
During our extended testing period, we kept a close eye on all the seals, connections, and the casing itself. There were no signs of rust, corrosion, or leaks. The unit feels engineered for longevity. The internal thermostat and heating element are well-protected within this robust shell. This solid build provides peace of mind that you’re investing in a piece of equipment that is designed to last for many seasons, not just a single summer. This commitment to durable materials is a major reason we feel confident in its long-term value, and you can check the latest price and availability for this robust unit online.
What Other Users Are Saying
Our experience with the FOKH 5.5Kw Pool Heater was overwhelmingly positive, but we always look to wider user feedback to ensure our findings are representative. The feedback available is limited but points to one specific area of concern that buyers should be aware of. We found a report from one user who noted, “The item is damaged on unpacking. The packing was not damaged.” This is a crucial piece of information. It suggests that while the external box might look fine, rough handling during transit could potentially damage the internal components.
This reinforces our recommendation to conduct an extremely thorough inspection of the unit immediately upon its arrival. Check for any loose parts, dents in the casing, or anything that seems out of place before you even begin the installation process. This user’s experience serves as a valuable reminder to purchase from a reputable online source with a clear and fair return policy. While our unit was flawless, this feedback highlights a potential pitfall that vigilance can help you avoid, ensuring you get the high-quality, functioning product you paid for.
How Does the FOKH 5.5Kw Pool Heater Compare to the Alternatives?
No product exists in a vacuum. The FOKH 5.5Kw Pool Heater offers powerful electric heating, but it’s important to understand how it stacks up against other popular heating methods, particularly the widely available solar and lower-power electric options from brands like Intex.
1. Intex Solar Heating Mat
- Eco-friendly Solar technology.
- Increases pool temperature by 3-5 degrees
The Intex Solar Heating Mat operates on a completely different principle. It uses the sun’s energy to warm water as it passes through the black matting. Its biggest advantage is the zero running cost and eco-friendly operation. However, its performance is entirely dependent on strong, direct sunlight, making it a very inconsistent option in the UK. It’s best viewed as a “season extender” that can provide a gentle temperature boost of a few degrees on a hot, sunny day. It is not an on-demand heater and cannot achieve the high, stable temperatures of the FOKH unit. This is a good choice for the budget-conscious and environmentally-minded user with a small pool who has realistic expectations about its limited power.
2. Intex Pool Solar Heating Mat
- 1m x 1m surface to absorb sun's rays Dimensions before filling 1.20m x 1.20m.
- Includes 32mm hose attachment points and 2 B adapters for use with 38mm hoses
This is another version of the popular Intex solar mat, designed for above-ground pools and featuring standard 32mm hose attachment points for easy integration into Intex systems. Like its sibling, it offers a free and green way to add a little warmth to your pool. You can even connect several mats in a series to increase the heating surface area. Despite this, it shares the same fundamental limitation: it is entirely reliant on the weather. On a cloudy day, it does virtually nothing. It cannot compete with the raw, all-weather power of the FOKH 5.5Kw Pool Heater, which can heat your pool on a cool, overcast day just as effectively as on a sunny one.
3. Intex Pool Heater
The Intex Pool Heater is a direct electric competitor, but it occupies a different performance category. It typically has a lower power rating (around 2-3Kw) and is designed for very small Intex or Bestway pools, often under 8,000 litres. While it’s easier to install, often plugging into a standard outdoor socket, its heating capability is significantly lower than the FOKH model. It will take much longer to heat a similar volume of water and will struggle to maintain temperature in cooler weather. For anyone with a pool approaching the 8-13m³ capacity of the FOKH, the Intex heater would be severely underpowered and inefficient, making the FOKH the superior choice for serious heating.
The Final Verdict: Is the FOKH 5.5Kw Pool Heater Right for You?
After extensive testing and analysis, our verdict on the FOKH 5.5Kw Pool Heater is clear: it is a powerful, effective, and well-built heating solution for owners of small-to-medium-sized pools (8-13m³). Its stainless steel construction promises years of reliable service, and its 5.5Kw element, managed by an intelligent thermostat, delivers the on-demand heat needed to truly conquer the unpredictable British weather. It successfully transforms a pool from a seasonal novelty into a consistent source of fun and relaxation from spring through autumn.
However, this performance comes with a critical caveat: the non-negotiable need for professional electrical installation. This is not a simple plug-in appliance. If you are prepared for this essential setup step and your pool falls within the recommended size range, we believe this heater represents excellent value. It provides the power and reliability that solar mats and lower-powered electric heaters simply cannot match. If you’re ready to stop letting cold water cut your pool season short and want to unlock the full potential of your backyard oasis, then the FOKH 5.5Kw Pool Heater is an investment we can wholeheartedly recommend.
