Gas Water Heaters

A gas water heater or gas fired water heater is used to produce domestic hot water for your flat, house or commercial property. This hot water is of sanitary quality and is used to feed showers, baths, and hot water taps or faucets.

Water heater gas fired

One of the many benefits of a gas water heater is the energy delivery that it can dissipate into the water and thus the good flow rates they can achieve when compared to instantaneous electric water heaters, which require a lot of Amps and normally a three-phase electric supply to achieve similar flow rates.

Gas fired water heaters

Our entire range of gas fired water heaters can be powered by either mains gas (also known as natural gas) or LPG (propane gas), which is your liquid gas. It is easy to convert our gas fired water heaters from one type of gas to another via a simple-to-fit gas conversion kit.

Hot Water Heaters

Gas fired water heaters can be split into two main categories:

On demand water heaters

On-demand, tankless water heaters or instantaneous water heaters will use less energy than storage water heaters and are the most energy-efficient method for heating water, with high performance mains pressure to all warm water outlets. However, the instant hot water flow rate demand and the usage of the hot water outlets by the customer installation must be considered to ensure they’ll work correctly. We go into more depth on this range here – instantaneous gas water heater

Storage hot water heaters

Alternatively, we do a range of storage water heaters; the two stock units have a water storage quantity of 150 litres, which is ideal for customers with a larger demand for domestic hot water, such as having a periodic requirement for a larger volume of water in a short period of time that an instant hot water heater couldn’t service with its flow rates. You simply need to store water for certain customers’ requirements.

Storage option – 28kW or 34KW output options

The “SFKA” range, as they are designated, is available in natural mains gas or as LPG as their fuel source and is available with an output of either 28kW or alternatively a 34kw output model.

They come complete with a 150 litre stainless steel storage tank, which has a long warranty, and all the associated plumbing pipework and a pump local within the casing.

They also have easy access for service or to maintain this reliable water heater unit as the panels are removable-with loads of room to get at and checkout the plumbing components that connect the heat exchanger of the water heater to the storage tank.

Thermal efficiency

In any domestic or commercial hot water heating system, any gas fired water heaters used these days must not only be a reliable appliance but also as efficient as possible.

This is where condensing water heaters come in as a solution with regards to gas fired water heaters, as you can recover the latent heat from the heater’s flue gases and recover that energy via a heat exchanger back into the hot water temperature-and not lost to the flue gases and the environment whilst saving the customer money.

Gas fired water heaters – Because the flue gases leaving the water heater are cool, they form a visible mist or plume of water vapour whilst leaving the flue terminal point or location

 

Because of this condensing process, our condensing gas water heater range are at least 15% more efficient than non-condensing systems. With the current high cost of energy, any customer may save significantly on their water heating costs by the installation of a water heater that will condense, whether in a domestic or commercial application.

Thermal efficiency or energy efficient ErP rating – “A”

 

This type of water heater is ErP “A” rated-and due to recent legislation changes, you must now fit condensing gas fired water heaters in all new and retrofit commercial water heating systems.

Gas water heater controls

You can use the thermostat built into the control panel on the device to set the hot water temperature output required, or alternatively, we do a remote temperature controller option too.
