Hi everyone,

been to look at a job, current set up is unvented cylinder with storage heaters. Customer has had a gas meter put in and wants a combi boiler put in. 1 bathroom and en-suite shower. She wants the unvented cylinder gone.

Job requires gas run in 28mm.

all new rads, valves etc. Not a massive property. 6 rads, 1 towel warmer. Downstairs on drops. 3 bedrooms.

Wirelesss stat.

Chemicals.

I know its a hard question to answer without seeing the job. 2 of us doing it, we don't seen any major hurdles. Looking for a ball park figure what you would all charge. We have a rough idea from getting a price for materials, have priced for budget rads and controls. I don't want to over charge but then I dont want to under charge and come unstuck.

Any pointers would be great. Thanks.
 
Shouldn’t this be in the gas safe only section and not the arms as we are talking about pricing a heating system (I know it isn’t about gas)
 
thanks for the replies, we'll have a chat tomorrow and see whats best. Unvented would probably be the best option. i'll see if the customer would be prepared to stick with unvented.
 
How many people live in the property?

I understand what people say when they say fit an unvented because its 2 bathrooms but if there is only say a couple living there then a combi will prob be fine just as long as they dont expect to both have a shower at the same time.

What is the flow rate like? I've been asked several times to fit a 40kw combi but the water flow rate was lower than what the combi could deliver so ended up with a 33kw.
 
What happens when the 2 people move out and 4/5 move in and hot water demand goes up?

What happen if they spend the next 60 years there?

I dont do work on my house thinking what will the next person want I do it for what I would like. If the next people dont like it they can change it.

I would say because you have 2 bathrooms I would advise that an unvented cylinder would suit the house better but as it's only the 2 of you living here then a combi would be fine for you as long as you realise that you will struggle to run 2 taps at the same time. If the next people dont like it because they have 6 kids then they can rip it out and fit a 400ltr unvented if that's what they choose.
 
Is that all I wrote? Maybe carry on reading the whole post before making stupid comments.
All I’m saying is in part you agree and then in others you don’t? No need to get shirty about it. Everyone has their own opinions and I was saying that it is best practice to fit a system with unvented when more than 1 bath or shower is fitted. What’s the point of having 2 showers if they cannot be used at the same time.

No but it's not best practice to fit a system with unvented when more than 1 bath or shower.

Best practice would be to install a system that meets the requirements of the customers and THEIR future needs.

And that is quite clearly what my post said.
 
uh oh what have I started lol 😕

To answer the questions
There's 2 people living in the property
It was the customer who suggested a combi.
 
We've just had a chat and he is adamant the vogue will be fine but said if i'm unsure then we will stick with unvented.

If she’s all electric, the unvented maybe/ probably a direct cylinder... so staying with it and using a boiler is a no goer.

Thought I would add to this thread

Just lost a job
BB and old system removed
New heating system with 5 rads and a duel fuel towel rail
Ecotec pro 28 with filter, lime fighter, shock arrester and VSmart controller
£5000

They have gone with someone fitting a WB30i and 10 years warranty for cheaper.
 
Yep complete dead wood here doing those jobs, firms here pay boys bottom dollar to slam them in. Reps have the fave firms as well so some pay half price on boilers
 
I was doing duotec full install for under 4k and made over a grand on each easily.
 
2 years ago. 6/7 rads and a duotec standard clock magna clean etc etc you can get most of it for under 2k
 
A Vaillant Ecotec pro 28 is over a grand - boiler only

I used to like vaillant but priced themselves out the market. Just fit baxi now. 630 with flue I'm selling for something like £930 that's with 10% on it.
 
Williams and co or Mr central heating

Never really rated William's, they were always good but the prices were nothing special. I use plumbase and city plumbing but go round and get your prices and make sure each know that you also go into other merchants so they fight to keep you.
 
just updated sorry lads plus

plumb centre and city will match

Thing I found with plumb center is they get you with a good deal like that then bend you over and pull your pants down on something stupid and you had to double check your prices all the time.

Which is what I have to do all the time.

How does that work?

contract support eg they buy alot through the year so they get decent / best prices prices same with these house builders you will find they buy the boilers as they get contract support as there building x amount of houses etc
 
If you take your quotes into screwfix they match or quite often beat the suppliers quotes.

You have to fit alot of boilers for contract support
 
Plumb centre charged me £28 for a vaillant pressure sensor about 5 years ago. Never stepped foot in another plumb centre since!
