hey up all,

thanks to Chalk - I managed to find a plumber who is going to follow his spec and we are finally back on track Wahey.

The duty point tank has come out mega expensive and I'm going to see how demand is for showers and install one in future if necessary (plumber is going to pipe everything in so it's easy to add a duty point tank in future).

He has recommended the following pump though: Magna3 26/60

Anyone know if this is any good? I know that Chalk had said I'd need a "suitably sized mains heating pump" - is that what this is?

Apologies in advance for the rookie Qs. (I don't want to Sod off Chalk by asking him so many Qs so am posting to broader forum)

you've had some good luck then if its sized right yes prefer dab myself but a pump is a pump

and i feel your going to need a pump sorry to say

hi @ShaunCorbs - is 26/60 the right kinda size? 42mm pipework will have up to 120 litres per min flowing through them in final state so want to ensure I'm using the right size pump.

hey @ShaunCorbs and @Chalked

I've had a plumber come back with a quote and wanted to get thoughts. Materials £7.5k for materials (excludes duty point) and £4.5k labour.

Reckons it will take him 150 hrs between 2 men to do the following. Does that feel about right?

Quote:

- pressure test (hallways, 4 bedrooms, 3 ensuites)
- Pipework for 1 bathroom inc. towel radiator, toilet, his/her dual basin, shower
- move Primary 25mm mains water supply 2ft to duty point location (duty point will not yet be fitted but only piping done to enable one to go in)
- move the Secondary mains water supply 1ft to plant room
- hook up the speed fit underfloor heating kit to heating system (builder already installed it in kitchen)
- install and commission the following equipment:

2 x 300l RM indirect unvented cylinder
2 x vaillant boilers giving a total of 60kw
Low loss header.
Suitable sized main heating pump
Mixing valve to give hot water priority
Vaillant sequence controller
Duty point pump set to give 120 lpm

42 mm primaries and connecting pipework
Motorised valves to all circuits

Might be missing something but what about the other 5 bathrooms and 4 bedrooms ?

We've split it between Phase 1 and Phase 2.
Quote covers Phase 1 (4 beds, 4 baths). Once that is done and system is in, phase 2 will involve doing the remaining pipework for the final set of 4 beds, 4 baths, 1 WC.

Sounds cheap on both labour and materials

Boilers alone and bits would come to 3-4K

Unless you have all the bathroom stuff ?
