Hi,
this is my first post, so please, be gentle.
We are in the process of buying a house we currently rent and one of the first jobs we need to do is change the boiler, as the current one is 20+ years old, and I can tell you it is really inefficient. (I think it was rating G when I checked it, but can't remember model name now). We had heating 24/7 this winter and still ended up with the ice on the inside of the patio door not melting away all day!
Also, we want to go from conventional to combi boiler, and get rid of the hot water tank, and header tanks in the loft.
The house is detached, 4 bedrooms, 1 bathroom + ensuite. (No utility)
Now, I know that some people don't like combi boilers, but we decided it is the way forward for us. By trying different calculators, I found out that 19kW would be sufficient for the heating needs of the house, but from reading around, it looks like 35KW would be suggested to deal with hot water demand.
I like to sound of EcoTec plus 937 with a small hot water buffer, it sounds like it would be able to deal with hot water demand if one of us is taking a shower whilst someone opens the kitchen tap, for example. One thing that bothers me - it is huge.
Another one that looks interesting (and a bit less intrusive) is Viessmann Vitodens 222-W, but I can't find much information about it. It looks like it has 46l primary cylinder, but I can only get more info on the floor-standing model, not the wall mounted one.
Does anyone have other recommendations? Do we really need an integral hot water storage/buffer? Any models to look out for and how to find a reliable engineer?
Any ideas of costs involved?... I think we will be replacing radiators at the same time, so that we end up with clean system (and no repainting). (There are 12 radiators of varying sizes)
