New boiler needed, not sure which type

pookiewn

Good Afternooon,

Could we have some advise on our new boiler set up as the existing boiler is on it's last legs and needs replacing. As we are renovating the house including the kitchen and bathroom at the moment and having to fix the previous owners mistakes! :eek:

Currently we have hot and cold water tanks and the newer extended parts of the house have poor water pressure however the original parts of the house are quite good. (We assume the prev owner didn't manage to break it too much)

Our current thoughts are:
Combi boiler and remove hot and cold tanks.
Underfloor heating on the ground floor.
Thermaskirt for upstairs.
Water softener.

Our concerns are:
Are there any issues with a combi and underfloor heating?
Can a water softener be used in this set up?
Can we have a decent shower without a pump?
Our lifestyle suggests a combi-boiler, would anything here preclude that?

Thank you in advance

Hi.


1) No.

2) Yes

3) Yes/no. depending on mains water flow and pressure available.

4) Yes, the number of hot water drawoff points will govern the suitability of a combi. Unvented hot water cylinder is the second choice.

Thank you.
Not sure which qualifies as a relevant drawoff point, but the list follows as:
Two sinks in the kitchen and dishwasher.
Utility room has a sink and washing machine.
Downstairs toilet has a sink.
Two basins, shower and bath.

There are only two of us in the house though. Should we be looking at Unvented hot water cylinder instead?

We seem to have got rather confused by the revision, was that yes to a combi assuming the water pressure is good enough? Is there a way of finding out what what our water pressure is?

The other half is looking at this WB boiler, any thoughts?

Thank you again

Hi.

Yes to a combi.

You would get definitive answers from an installer who can measure your water flow rate and pressure. Google for measuring flow rate.
You will need a pressure gauge to find .... pressure.

Personal preference is a boiler with a stainless steel heat exchanger, such as Viessman, Vaillant .Worcester being aluminium.
Worcester are good at marketing their product. If only they put as much effort into making the product easy to work on in the event of a part failure.
