Do I need new radiators for a combi boiler?
If you’re switching from a different type of boiler to a combi model, you might be wondering if you automatically need to switch to new radiators. In short, you don’t – unless there are problems with your current radiators. As long as they are functioning well, you can keep them in place.
How many radiators can a boiler handle?
As a guide, combi boilers between 24 and 27kW can power up to 10 radiators, while a 24kW heat only or system model can heat up to 15 radiators.
How close can a radiator be to the boiler?
The boiler is positioned in the corner of the wall just above the kitchen counter, the radiator would ideally then be placed below (just off the floor) roughly 70cm from the boiler. So it would be near but not directly below the boiler or the flue.
Why should radiators be under Windows?
Windows are traditionally the worst insulated surfaces in a building shell. In the twentieth century, to combat that cold feeling and keep the room comfortably warm, radiators were always placed under a window. The rising heat of the radiator forms a kind of hot air curtain that shields you from the cold air.
Can a solar hot water system work with a combi boiler?
Since both solar energy and combi boilers are a growing trend, the heating industry should know by now how to combine solar hot water systems with combi boiler system, however, it is still technically challenging to make this combination work. There are some combination boiler models that are compatible with a solar thermal system.
How much does an electric combi boiler cost?
The electric combi boiler itself will potentially cost around £2,000. This can vary greatly depending on the manufacturer and model. Popular electric boiler brands include Heatrae Sadia, Elnur and Electric Heating Company – compare the Best Electric Boilers.
How big does a boiler need to be for solar heating?

How does solar energy work in a boiler?
Therefore the water that is heated up by solar energy needs to be saved up for later use in an additional hot water cylinder. 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.

Do you need radiators for a combi boiler?
Combi boilers can offer an effective and efficient way to heat your home, and they give you access to hot water on demand. However, if you don’t have enough radiators or your radiators aren’t in the right places, you might be left feeling the chill in your home even if you have the perfect boiler for your property.
Where does the water go in a combi boiler?
For a conventional cylinder, where the water in the cylinder goes to the combi boiler, the most common approach would be a thermal pasteurisation of the water.
