Whether or not your solar thermal system can be matched with the combi boiler will depend greatly on the model of the boiler you have installed.
Can you use a combi boiler with solar panels.
If your model isn t listed you ll have to call the manufacturer and while you re at it please nag them to join in with this splendid industry initiative from the solar trade association and the hhic.
Electric boiler with solar pv.
As long as you have the required space for the cylinder there s no reason why you shouldn t go ahead as the payback.
You ll know you have this type of system as it appears as tubes arranged on your roof in rows as opposed to the more typical panels used for electricity.
Therefore tankless options such as combi boilers aren.
The solar energy available varies from day to day so it is also important to use the boiler to bring the water to a sufficient temperature on days without the contribution of solar energy.
The combi diverter valve ensures that the hottest inlet temperature the boiler will see is 27c so this can be a way to make solar preheated water work with any combi boiler so long as you can check that this temperature is ok for the model in question.
A typical solar thermal system will set you back around 4 000 but you will need to install a cylinder and extra pipe work with a combi so you can expect another 1 000 on top to make the solar thermal work with a combi.
Now consider the interest in borrowing 6 000 pounds.
The primary consideration for this type of solar system is the requirement of a boiler tank within which to store any heated water.
Combi boilers generally fall into two categories.
Solar panels can be heavy so your roof must be strong enough to take their weight especially if the panel is to be installed on top of existing tiles.
Naturally solar panels are only able to generate renewable electricity during the day which would mean having to rely on your energy supplier during the night that is unless you install a solar.
The solar thermal panels located on the roof have a fluid within them that gets heated by the sun.
Not all boilers are compatible with solar water heating for example if you have a combi boiler and you don t have a hot water tank.
As solar panels heat water across a day and not necessarily when there is hot water demand the need is still there to store solar heated water until you are ready to use it.
Solar ready fully modulating which can accept preheated water up to 60 c or non modulating which can typically.
Solar pv panels take in solar energy from the sun and convert it into electricity that can be used around the home.
