jut to make sure before i part with any cash, vaillant are a good reliable make, am i right ? i just want to make sure. also i don't have any option but to buy a storage combi. unless it really would be much better for me to get an un-vented system installed then i would make room for it but i...

I don't want another floor standing boiler as i feel it takes up too much space and have been told that they are more difficult to work on than wall mounted ones. The boiler is in a cupboard and i would like to have the floor space back to put stuff in. Thats whats putting me off the highflow...

It is not a contradiction i was merely stating what i wanted in my system. would you install a boiler which was not suitable for the system it was being installed into ? I have a highflow heatslave that can supply 2 bathrooms simoultainously. Although we never run two baths we run two showers...

sorry i worded that wrong, what i mean is that one of the deciding factors will be about reducing my bills by installing a more efficient boiler. i assume that my old highflow heatslave is extremly inefficient considering it is over 14 years old or there abouts.

I just looked on vaillants website and they say that the integrated storage of 15litre (which is the same as the highflow i have) can delivered over 200 litres of water in 10 mins. The ecoTEC plus 937 has a central-heating output of 12 to 28 kW and a DHW output of 37 kW. So would this be a...

i thought fitting a new condensing boiler would reduce my gas bills ?

so is fitting a 37 or 42 CDI goin to increase my gas bills ? :shock: I already pay £180 per month. what about the valliant someone suggested ?

will the 42 cdi give me 17lit all the time ? if so would it be ok to fit the 42 cdi or would it be oversized for my requirements ? as for my loft it is too low to fit in an unvented cylinder and there is nowhere to run the pipework for it without it going up walls and needing to be boxed in. i...

I understand what you are saying, but the current combi i have suits my needs and will let me run two baths at the same time. The thing is i only have the space where the old boiler was, no room anywhere in the house for an unvented cylinder. and want to fit a similar combi because my old...

Thanks for the speedy reply but the problem i am having is the space, i don't have room for an un-vented cylinder. The only room i have is the cupboard which the boiler is currently in. The plumber originally suggested a viessman vitodens 300 26kw and and a megaflo 210 HE but as i don't want a...

I have been advised to replace my boiler and am going to replace all my rads with reproduction cast iron rads to suit the style of the house. I currently have a worcester highflow heatslave which has been in the house for about 10+ years before i moved in it is rated at 38kw. I have two...
