Ahhh is there an M&E plumbing contractor in North East that can help me

[ShaunCorbs]

1, down to personal opinion and what your budget is my preference is gledhill

StainlessLite Plus Indirect - Gledhill

2, very good (my brand of choice) but thats a combi you have linked / talked about, you want a heat only boiler/regular

something like this

Worcester Greenstar 40CDI Classic Regular ErP Boiler

Vitodens 200-W wall mounted gas condensing boiler - Viessmann UK

ecoTEC plus - Vaillant

3, wouldnt go with weather comp, just invest in a decent simple control system (chalked im sure will agree with this)

Hi
Your missing quite a lot
My spec was
2 rm 300 cylinders or preferably ACV same size.
2 vaillant system 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

This will need 42 mm primaries and connecting pipework
Motorised valves to all circuits

Think you may find your closer to £10,000 for materials
Regards
Paul

Hey thanks! What size should the main heating pump be in your opinion & any recommendations for a brand I should go for?

Finally, if 42mm primaries go in, what would you recommend secondaries at - 22 or 15mm?

Chalk is on the right track N14 dump the worcester wave and you will need a bespoke control panel built to control your system time, tempreture control and weather comp will be built in this with a programable room thermostat in each room this may help you the last two projects i did we used Ideal Evomax worked very well . wishing you all the best kop

Just had a bad kock with there customer services and warrenty, so wouldn't recommend them

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)

 

[ShaunCorbs]

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

 

[n141311]

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.

depends on size of property but he will know what size or im sure grunfos do a sizing app or calc

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.

 

[ShaunCorbs]

Sounds cheap on both labour and materials

Boilers alone and bits would come to 3-4K

Unless you have all the bathroom stuff ?
