Solar panels sound like a good idea if you have a traditional boiler and water tank system, because you can store the solar heated water.
BUT I would like to know if you can use a solar panel with a combi boiler? The type that only fires up, on demand when you turn on a tap?
In effect you are preheating the mains water before it gors into the boiler. Is this wise? Safe? cost efficient?

- Help we have low water pressure and need a new boiler, we currently have a combi so no tanks any suggestions?
The combe boiler we currently have keeps going faulty, we have low mains water pressure and have been told a combi isn’t suitable. We have no water storage tanks. Anybody know what boiler type to recommend.... - Combi Boiler Water Pressure Issues?
We recently had a combi boiler installed in our rented property. Initially the plumbers left the cold water feed from the tank in the loft so the combi boiler was only supplying the hot water. Unfortunately due to the differing pressures (i think), the cold water feed was excessive whilst using the shower the overflow pipe from the loft rained from the side of the house. The plumbers have since rectified that problem by removing the cold water tank and using the boiler to supply both the hot and cold. Unforunately the water pressure is now so low that it takes 30 mins to fill the bath. Also the shower now operates too hot and eventually (after a few mins) runs cold then hot again.

I want to put the combi boiler in the basement and use the hot water side to feed the kitchen,utility room and downstairs shower room whilst siting the water cylinder next to the bathroom on the first floor to serve that room and a shower in the loft. Is this a sensible use of a combi or should I use a system boiler and just take hot water from the unvented cylinder?... - Ideal classic combi 80 boiler, low pressure, loads of noise, no hot water?

This is a question for the solar panel manufacturer. Combi water flow is quite fast. Maybe not the optimum speed to pick up solar heat. Also the water would be at mains pressure which again may not suit the panel. Regarding input temperature to the boiler, I can’t see a problem there.
