Bespoke Direct Gas Fired / Solar Thermal Hot Water Packages

Working with our well established solar partner our bespoke direct gas fired water heater / solar thermal packages offer an ideal solution for building owners who wish to reduce their carbon footprint without compromising the hot water supply.

Packages include:

  • Bespoke design - packages individually designed to meet the specific requirements of your particular building
  • High efficiency evacuated tube or flat plate collectors
  • Compact, lightweight design - saving installation and maintenance time and costs
  • Single and twin coil vessels
  • Supply and install or supply only options.

Solar collectors

There are two basic types of solar thermal collector; evacuated tube and flat plate. Evacuated tube collectors are better suited to our northern hemisphere climate and can offer higher overall efficiencies compared with conventional type collectors. The compound parabolic concentrator (C.P.C) reflector fitted to the rear of the tubes allows direct and diffuse radiation to fall onto the collector even when the angle of the sun is not at its optimum. This considerably improves the energy yield of the solar collector.

Pre heat storage vessels

A suitably sized pre heat storage vessel is required in order to maximise any solar gain. The use of a single coil pre heat vessel feeding either a direct gas fired water heater or calorifier is the most efficient way of storing solar energy as the store is not compromised by having to serve two seperate purposes. We can provide a comprehensive range of single and twin coil storage vessels with capacities between 150 - 3000 litres. Larger capacity and specialised storage vessels are available on request.

Typical direct gas fired water heater/solar thermal schematics

Primary heat source

For the majority of commercial and industrial applications utilising solar thermal, approximately 40-50% maximum of the buildings hot water demand could be satisfied by solar energy, and therefore it is important not to ignore the primary heat source.

Our complete range of water heaters, and in particular our condensing models with efficiencies between 92% - 99% Gross CV, will ensure the most efficient use of fossil fuels and thus help you achieve higher reductions in emissions of CO2
