ThermaTwin is a unique flat plate solar thermal collector, which uses the power of the sun to heat the water and power the pump and controls.
As a result the system is completely off-grid, and maximises the total energy available to service the needs of the home whilst reducing the carbon consumed during operation to effectively zero.
Manufactured in the UK, ThermaTwin offers a robust, practical and affordable solution to your hot water and heating requirements.
Usually installed in under a day, ThermaTwin provides a simple, maintenance free, robust and reliable system that can provide up to 100% of your hot water during the summer, 70% during Spring & Autumn and up to 30 % during the winter – absolutely free.
By eliminating the use of glycol or anti-freeze, the ThermaTwin panel needs no refills or level checks, as it uses the direct mains water feed into the property. The panel uses a unique freeze-tolerant pipe that eliminates the need for drain back or other complicated control systems; fewer moving parts and controls means less maintenance and less to go wrong. This mains water is heated by the thermal panel and pumped directly into the hot water tank using the on-board PV panel as power for the pump, with minimal plumbing or disturbance.
It makes it an ideal bolt-on to the 1,000,000’s of homes in the UK running a non-pressurised system and header tank, as no heat exchanger is required, boosting overall system performance and reducing installed cost.
Where more than one heating source is installed, DiscreteHeat can provide a range of Multi-fuel Thermal stores, designed to take hot water from a variety of fuel sources as well as the ThermaTwin solar panel. These could be gas, oil, electric or biomass boilers or indeed a heat pump.
In smaller properties utilising a combi-boiler, DiscreteHeat can provide a compact pre-heat thermal store, especially suitable for combi’s. Up to 120L of preheated water can be stored, (usually enough for a 2-3 person property), which reduces the amount of gas required to service the house to an absolute minimum. Thermal Stores are available to enable ThermaTwin systems to be installed in conjunction with pressurised sealed boilers.
All ThermaTwin systems are supplied with an in-line electrolytic filter to minimise limescale build up. In areas of harder water (80 -180 ppm of calcium carbonate) we recommend the use of scale reducing crystals (Fernox LSP or similar).
For very hard water areas (180ppm or above) DiscreteHeat recommends a water softener and/or a thermal store, which the company can supply.
