Mis sold a combi?

[panthro]

I have a 4 bed house, with a family bathroom, en suite and downstairs toilet.

We used to have a traditional boiler in the kitchen and a tank in airing cupboard.

Plumber suggested replacing with a large combi in loft.

Have we been mis-sold this setup? After searching online people seem to not recommend a combi for this size house?

Thanks

Has the job been done?
It depends on your hot water useage

The job has been done. Surly it depends on the size of the house, as work was done with the intention of selling in the future.

If your only using one outlet at a time / one shower etc then it’s ok / good enough

If you're not happy with the performance of the current arrangement it should be fairly straightforward to install an indirect unvented hot water tank in the airing and use the combi to heat it.

We had a perfectly working tank in there, he got rid of it, im not paying for a new one.

No a combi is sized on hot water
Are you not happy with the performance?
What make/model & size boiler is it?

Takes some time to get hot water from taps. It's a worchester 36cdi.

How long we talking as if the copper pipe hasn’t been used for a while that’s normal also you would of had this with your old system

10 seconds, i thought it would take longer as the boiler is now installed in the loft not the kitchen (installed here under plumber's guidance).

You keep mentioning that it's installed under the advice of the plumber. We get that. We're not going to argue that, so I think we get the picture there. No need to keep mentioning that I don't think.

What is it you'd like out of this thread, and situation in general?

The distance from the old system to taps, and new system to taps, is more to do with the length of copper moreso than the actual physical distance. So I wouldn't assume just because it's in the loft, it's further away copper-pipe-length-wise.

If you're unhappy about it, then I guess the first thing to do is to put it in writing to your plumber, and have them respond in writing. So you're both on the same page as to how this came about.

With regards to fixing your issues, you need to find out what they actually are first. And have that in writing.

I'm not a plumber by the way. Don't take my advice as the going rate.

Using a combi in a house of your size is just on the cusp of unsuitable. Other factors such as mains water pressure and volume also have bearing, big combis might have the specification to deliver adequate volumes of hot water but if your home or utility cannot supply an adequate supply of mains water then there might be your problem. Installation in the roof might well compound the poor pressure/volume issue. I Have had to rectify this problem before and would not put any boiler in the roof esp. combi as they need a bit more maintenance than conventional systems coupled with the requirement for access to the boiler must boarded out for safe servicing. centralheatking

As mentioned, it depends on your hot water usage. Firstly, how many of you live in the house? What does your family bathroom and ensuite consist of? Do you have an electric shower in one? What's your flow rate and pressure like and as mentioned before, what is your issue with the boiler?

10 seconds is well within the standard expectation, which is that when opening a hot water tap the water should reach 50°C within 30 seconds.

Don’t worry about what others say, I’m sure if I Googled my van, phone etc I’d find 1000 posts with tales of woe. It sounds like your new boiler is doing the business to me.

If your not 100% happy your first port of call should be your installer. It may well be there are subtle factors that lead them to suggest a combi rather than a system boiler. Give them the chance to put your mind at rest.
