Gas fired water heaters from Flexiheat UK; tap; gas water heaters; gas fired hot water cylinder

This series of gas fired water heaters, are condensing water heaters that have a storage capacity of 150 Litres and are extremely energy efficient – higher than 105%. The water heaters storage volume has been designed to provide enough instant hot water to the hot water heating services such as taps, showers, or filling baths at a constant temperature and flow rate, that you can’t achieve with multi point water heaters, which can suffer from low flow rates.

These water heaters deliver a reliable solution for larger domestic or commercial applications such as restaurants, shops, health centres ,fast food outlets, and pubs that demand good flow rates of warm water, for their use or their customers.

We do two models within the “SFKA” water heater range as it’s designated – These products are ErP “A” rated for efficiency condensing water heater and are sometimes called a gas fired hot water cylinder.

28kW gas fired condensing water heaters– with a 150 Litre stainless steel storage tank – Which will provide a continuous D.H.W. supply – ΔT 30°C hot water temperature – of mixed water , in  1 hour of 984 Litres of flow rate – and a first 10 minute flow rate of 305 Litres

Or

34kW gas fired condensing water heaters – with a 150 Litre stainless steel storage tank – Which will provide a continuous D.H.W. supply – ΔT 30°C hot water temperature – of mixed water , in  1 hour of 1,167 Litres of flow rate – and a first 10 minute flow rate of 333 Litres

Both heater models are available in natural or propane (LPG) gas powered options.

However, should have domestic hot water flow rate on the lower side, then please look at our webpage – gas multipoint water heaters – these are condensing gas instantaneous water heaters or flow water heaters with stainless heat exchangers which provide instant hot water performance without the need for hot water storage cylinders as they may be a better water heater solution, even in commercial water heating applications.

This water heater natural gas or lpg fired range are commonly used for feeding shower systems directly without the need for boilers and indirect calorifiers systems.

Condensing Water Heaters – ErP “A” rated

A highly efficient condensing gas fired continuous flow water heater is combined with a well-insulated stainless steel water storage tank to make one complete gas storage water heater / water heating system – that provide excellent flow rates- something instantaneous electric water heaters can not achieve. We have a models replacement tool / bim models replacement should you wish to replace another manufacturers products ( such as a rinnai water heater or boiler)  dhw heater or heating systems either condensing or non condensing products.

This ensures occasional times of peak hot water usage can be satisfied by combining a condensing large capacity water heater with a domestic hot water storage cylinder, in an efficient gas fired water heater range. These condensing water heaters are highly energy efficient and are a perfect replacement for an instantaneous electric water heater which at this output require a lot of Amps to feed the units, and are therefore not practical.

Gas fired water heater product information

Compact, stand-alone water heating appliances or units for producing safe and clean domestic hot water –

Gas fired (hot) water production – sanitary quality hot water –  suitable for larger houses to commercial and industrial applications.

Water heaters that run on natural gas (mains gas)or LPG ( propane )are available.

Reduces energy consumption and operating expenses by optimising condensing water heating performance. With an energy efficiency higher than 105%

The stainless steel heat exchanger with a 28mm diameter and a modulating gas burner minimize the possibility of scale build-up.

It benefits from very low pressure drops, guarantees lower risks of clogging, greater thermal efficiency, and greater ease of cleaning of this condensing water gas fired range.

Closely matches water demand and water temperature, with 1:9 modulation for greater efficiency and reduced energy consumption for your desired temperature.

These are direct fired gas water heaters, so there’s no heat exchanger coil located in the storage cylinder,

The inbuilt pump ensures even heat distribution and reduces the chance of stratification in this direct fired water heater range.

No clearances are required at the back, and minimum clearances at the top and sides allow for installation in any location or a plant room.

Making these commercial gas water heaters a great solution for heating water when space is limited.

Suitable for LPG gas combustion –

Can be fired by propane gas – With a maximum gas inlet pressure of 45 mbar for these commercial products

Suitable for mains gas (natural gas) combustion –

Can be fired by natural gas – With a maximum gas inlet pressure of 25 mbar for these commercial products

Enhance functionality and reliable control function –

You can use the inbuilt control panel or use an “OpenTherm” compatible controller for local or even remote management via a PC, tablet or phone of our gas fired water heaters. They can also be connected to a separate BMS system, using a 0-10V communication card.

Anti-legionella systems –

A vital safety function ensures that the gas water heaters storage tank is taken above the temperature required to kill any legionella in the gas water heater.

Flexible and multiple flue options –

This range of gas powered water heaters can be room sealed with a co-axial flue system, or up to a remarkable 60 metres when using a twin flue system, which is a great provision when being used in a commercial site or industrial applications

Storage tank anti-freeze system –

To ensure safety and that the water heater functions properly, the water heaters have an inbuilt sensor that automatic detects a water temperature below 5°C, the pump activates and the gas water heater raises the water temperature up to 30°C.When this temperature is achieved, the burner turns off and the pump runs for a further 20 seconds as post circulation for these water heaters gas fired.

Solar water heater

By adding our solar water heater kit, you can supplement these gas fired hot water heaters with solar energy. Solar water heating is of course carbon neutral. Our solar kit, will control the solar panel pump and take a signal off the solar panel temperature probe on these commercial gas fired products.
