new CH system in 2 bed cottage

[daviesmw]

i need a new CH system to be installed in my 2 bed cottage which will have one upstairs bathroom. Will a combi boiler be sufficient for this (bearing in mind that i would like a decent power to the shower) and what kind of output should i be shopping around for (BTUs?) and make of boiler?

Thanks

I would search for a heat loss calculator on the net, enter your measurements etc. This will give you some idea about BTU requirement from the heating side. Not sure about the HW though. I think Kermi do a good free calculator.

BTU requirement will vary depending upon the construction of the cottage. As the owner, you will have a better idea than us

For the ho water you need minimum 28kw and get the installer to range rate the heating side of the boiler appropriate to your small dwelling..

Agreed as long as your mains is good flow and pressure. Combi should be fine if there are only a couple of people and no. 2 remembers not to turn a tap on while no. 1 is in the shower

Which combi - a bit of a lottery as they're mostly quite new just now. Ideal Isar is small and seems to be a stable product now. Otherwise most would say Vaillant, WorcesterBosch, councils are using Potterton/Baxi.
