New boiler

Nebulous2

Hi folks - looking for advice on a new boiler/ heating system with rough costs.

The scenario is 20 year old semi, with original boiler / heaters. Boiler situated in kitchen on ground floor, water tank in loft, hot water cylinder on first floor, two showers on first floor. Mostly microbore plumbing, some thermostatic valves a bit dodgy. One additional heater installed in a converted room about 14 years ago with 'normal' piping.

Options seem to be:-

1) straight replacement / flush / replace dodgy valves.

2) Replace with new radiators, piping etc

3) Replace with combi, remove tank in loft, remove cylinder.

I quite like 3 if costs stack up, but worried about having to redo bathrooms. That would be on the cards in maybe two years anyway but reluctant to pay it now.

Would a combi boiler feed two showers at the same time, or would I need electric showers?

thanks

A combi will not feed two showers at the same time; some can struggle to produce a decent flow for one in winter.


Whilst electric showers are relatively cheap, the wiring for Retro-fitting electric showers can be quite complicated and therefore expensive. It will require heavy duty wiring from a 40 or 45 amp RCD on your consumer unit, or a new consumer unit.

Thanks - so it looks like replacing like-for-like would be my best option. I'll try to get some prices and take it from there.

I would replace the microbore when refurbishing the whole house. If this is not the time, then just clean the pipe work with Fernox F3, preferably having put in aTF1 filter.

24, 28, 33, 40kW, take your pick.


You can leave the microbore alone and do a partial boiler replacement.


Supply the 1st floor bathroom using the cylinder as before.
Supply hot water from the combi to the kitchen and ground floor bathroom. A good backup configuration, you heat the cylinder electrically if the combi fails.
