C - combi systems
Providing mains pressure hot water that integrates with your existing combi boiler. The exact specification of the system will depend on wether your combi boiler can except preheated water or not. This will be decided when your technical survey is carried out. Most of the modern ones can.
If your combi boiler cannot except preheated water then we will install your system with a 2 two port valve arrangement. What this means is that when your new un vented solar cylinder comes up to temperature ie: 55°c then the valves will divert the supply of your hot water from your combi boiler to your solar cylinder. The cylinders come as standard with a mixing valve to ensure the temperature never exceeds a safe temperature at your taps. Your boiler will not have to heat any water on demand at this time as this hot water will at your taps will have come from your solar system.
If your combi boiler is heat sensing then we use a patented combi valve solution. These operate in three ways:
- If your solar cylinder is at the target temperature of 55°c or above then the valves will mix this down to the safe target temperature of 55°c and send this water directly to your taps bypassing your combi boiler.
- If your solar cylinder is below the target temperature of 55°c but above the temperature your combi boiler can safely accept as preheated water, typically 30°c then the valves will mix this down to 30°c and feed it to your combi. Hence your combi boiler only has to heat the water an additional 25°c to get to 55°c. And you boiler can do this safely.
- If your solar cylinder is below the temperature your combi boiler can safely accept as preheated water then the valves allow the preheated mains water directly to your combi boiler. Any amount of preheat in the water reduced the load on your boiler.
As your combi boiler operates on mains pressure water we need to install an un vented cylinder. All solaressence® un vented cylinders are stainless steel and come with a 25 year warranty. An additional benefit of installing a solaressence® cylinder is that it each cylinder is custom-made for your home so can be manufactured to fit snugly into the correct space. These cylinders are also much more highly insulated so you lose less energy with the heat escaping. It must be noted that there must be some where in your home to house the cylinder, an old airing cupboard, garage or loft space.
Substantial savings on your hot water costs can be made because the energy you receive from the solar system into your hot water supply displaces the energy your boiler would otherwise have had to produce. Plus you have the ability to upgrade at any time in the future to a dual system should you install a new condensing or system boiler.
