Water Heating

Water heating solutions for your existing system or a new build.

Whether you’re trying to improve your existing system or need a complete solution for a new build, we’ll advise you on the best options for your requirements, considering both cost and efficiency. Like your room heating, the design and implementation of your water heating at a very early stage of the planning process is critical. Deciding factors often include: installation cost vs running and maintenance costs; use (domestic supply and/or central heating); and environmental impact.

Take a look through some of our more recent projects to view the range of heating solutions on offer.

Gas & Diesel Boilers

Gas & Diesel Boilers

WHAT
Gas and diesel boilers work by burning fuel to heat water, which is transferred into domestic hot water storage and/or through central heating pipework.

WHY
Energy efficient, reliable source of heating.

Running costs are relatively low (depending on fuel prices) and capital cost to install is less than a heat pump.

WHO
Particularly suitable for as a combined water heater for central heating and domestic hot water.

Install cost: Medium.

Running cost: Medium – cost of gas or diesel.

Maintenance: Annual servicing recommended.

Central Heating or Domestic Supply : Both.

Gas Boiler

Gas Combi Boiler

WHAT
A Gas Combi Boiler is a combined gas boiler for central heating and instantaneous gas water heater for domestic hot water.

WHY
Energy efficient, reliable source of heating.

Running costs are relatively low (depending on fuel prices) and capital cost to install is less than a heat pump.

Negates the need for a domestic hot water cylinder.

WHO

Particularly suitable for as a combined water heater for central heating and domestic hot water.

Install cost: Medium.

Running cost: Medium – cost of gas.

Maintenance: Annual servicing recommended.

Central Heating or Domestic Supply : Both.

Air Water Heat pump

Air-water Heat Pump

WHAT
An Air-Water Heat Pump works by extracting heat from the outside air and converts the energy to heat water.

WHY
Highly efficient – initial set up cost is more but running costs are comparatively low.

Environmentally friendly – doesn’t use fossil fuels to run. Can be used in combination with Solar PV system to offset power requirements.

Works even when outside air temperature is as low as -15° outside.

WHO
Run most efficiently when heating water at a low temperature, so best suited for underfloor central heating.

Install cost: High.

Running cost: Comparatively low – cost of electricity (high efficiency)

Maintenance: Annual servicing recommended.

Central Heating or Domestic Supply : Both.

Rotex Sanicube

Rotex Sanicube (Thermal Store)

WHAT
An advanced water heater and water storage unit combined, the Rotex stores 500L of water. Set up can be customised allowing for integrated heating and energy solutions.

WHY
90mm thick insulation results in excellent heat insulation values. Hot water can be stored up to 5 days, maximising efficiency.

Water can be heated via a boiler or heat pump and introduced via heat exchanger, or electric, solar or wetback coils can be integrated.

Coils can be retrofitted and replaced if required.

WHO
Excellent option for central heating systems when larger amounts of hot water required, or integrated systems using solar collectors. Also used as an upgrade from a standard electric hot water cylinder for domestic hot water supply.

Install cost: Medium.

Running cost: Dependent on set up.

Maintenance: Dependent on set up.

Central Heating or Domestic Supply : Both.

Air Water Heat pump

Continuous Flow Gas Water Heater

WHAT
Works by burning gas to heat water as it flows through the unit, on a supply and demand basis. Can be located internally or externally.

WHY
Provides unlimited hot water. Quick to heat up.

Cost effective to run as hot water doesn’t need to be stored.

Can install multiple units in larger properties so hot water can be provided quickly in different areas.

WHO
Suited for domestic hot water supply.

Install cost: Low.

Running cost: Medium – cost of gas.

Maintenance: Nil – filter cleaning recommended.

Central Heating or Domestic Supply : Domestic Only.

Wood Boiler

Wetback

WHAT
A wetback is a pipework system installed behind the fire which heats water as it travels through the pipes. The hot water circulates through a wetback coil in the cylinder, to heat the stored water. Can be installed with specific fires.

WHY
Heat your water and your home at the same time – use excess energy by converting it to hot water.

Inexpensive and environmentally friendly water heating.

WHO
Particularly suited for smaller water heating requirements e,g domestic hot water or a few radiators.

Install cost: Low.

Running cost: Low.

Maintenance:  Nil.

Central Heating or Domestic Supply : Suitable for radiators.

Wood Boiler

WHAT
A wood boiler/stove is a fire with a wraparound ‘jacket’ which water is heated through. This means the water is heated over a larger surface area than wetback pipework.

WHY
Heat your water and your home at the same time – use excess energy by converting it to hot water.

Powerful, quick to heat and efficient – can run up to 10 radiators while providing radiant heating.

Inexpensive and environmentally friendly water heating.

Very low maintenance and simple design.

WHO
Can only be used in rural or rural residential zones to comply with clean air standards.

Solar Collector Panels

Solar Collector Panels

WHAT
Panels on roof collect heat which is then transferred to pipework circuit/solar coil in hot water storage unit. The heat is then transferred from the hot water in coil to the water being stored.

WHY
Environmentally friendly water heating.

Very low cost to run.

WHO
Suitable for domestic hot water supply as a source of water heating with backup required (supply will fluctuate depending on sunlight hours).

Hybrid panels which produce power and hot water are available. These are extremely efficient panels (83%) providing much hotter water. Excessive for standard domestic use, these panels are suitable for ground source heating e.g. for accommodation.

Technosolis solar collector panels are available specifically for swimming pool heating.

Install cost: High.

Running cost: Low.

Maintenance:  Annual Servicing Required.

Central Heating or Domestic Supply : Both.

Groundsource

Groundsource (Geothermal) Heating

WHAT
Ground source (geothermal) heating works by water flowing through a series of pipes run below ground. The natural ground temperature heats the water which then passes through a heat pump to increase the temperature to a point it can be used for central heating and/or domestic hot water.

WHY
Environmentally friendly water heating.

Heat pump is highly efficient method of water heating making the system comparatively very low cost to run with a higher capital cost.

Cost to run heat pump could be offset with Solar PV.

WHO
Excellent for lodges, accommodation etc, or for environmentally friendly projects. Suitable for central heating and/or domestic hot water.

Install cost: Very high.

Running cost: Comparatively low – cost of electricity (high efficiency)

Maintenance:  Annual Servicing Recommended.

Central Heating or Domestic Supply : Both.

Hot Water Cylinder

WHAT
Water storage unit that can be fitted with various coils for water heating options, including electric (standard) and solar and/or wetback. ​Available in various sizes to suit.

WHY
Suitable for low or mains pressure water systems

Simple and low maintenance

Lowest priced water heater

Electricity use can be offset with solar PV panels.

WHO
Hot Water Cylinders are generally necessary for hot water storage in all homes (unless continuous gas is being used).

Install cost: Low.

Running cost: Medium – cost of electricity.

Maintenance:  Nil.
