3/4 bedroom house (loft conversion) central heating system

[NL1981]

We're moving into a 3 bedroom house and are planning to convert the loft into a 4th room with ensuite shower, wc and basin.

The current central heating system is obselete and needs upgrading. We would therefore be looking to have a new system consisting of approx 8 radiators and 2 towel rails as well as supplying hot water to both the main and en-suite bathrooms.

Would a combi-boiler be suitable for this? A lot of reviews we have read suggest that combi-boilers are more suited to smaller homes (2/3 bed, 1 bath) with lower hot water requirements as the pressure becomes compromised. We're literally starting from scratch here so are open to all suggestions!

Also any ideas on what boilers would be most suitable would be greatly appreciated. Apologies for the essay, but thanks in advance for your comments!

It all depends on the dynamic mains supply flow what can be used.

A combi will hardly supply two outlets at the same time.

This has been discussed so many times on this forum. Why not search an dread all the information.

Better still get a competent installer to visit to assess whats possible. Best on a chargeable basis.

We dont make free visits to specify systems but we do give budgetary quotes over the phone. Only those short of work do free visits, think why some may be short of work!

Combi boilers are best suited to homes where you will not have two separate demands on hot water at the same time. In a pinch you can get a big powerful combi that will maintain a decent shower while the kids play with the taps, even two showers at once provided you don't want to be knocked over by them, but you should consider other options if that is going to be the norm rather than the exception.

Mains water will usually work a loft shower without any trouble but you should certainly check before you make any major decisions. With tank and cylinder fed systems you would obviously need a pump on the shower Also consider the shower you would like. Combi boilers provide a high pressure shower but will not be able to cope with very high flow rate showers. Storage combis can provide a flow rate as high as most single-head power showers, but only for a limited time. Gravity fed cylinders can provide a very high flow rate but only limited pressure, but you can fit a pump to add pressure. Again there is only a limited amount of hot water available and you can burn through it in just a few minutes with two showers going, but you would size your cylinder to suit your needs.

There are many different types of heating systems available nowdays anything from storage combination boiler ,solar with unvented to myriad of other alternatives

I suggest you call professional heating company who will come in and discuss your requirements for the system that needs to be installed into your home

Most professional businesses will come and do a free visit to discuss this and it has absolutely nothing to do with wether they are busy or not,Tony agile is more of budget boiler repair man and has some weird views on companies who have professional installation teams and go that extra mile for their customer.I have been known to go to customers houses late in the evening and at weekends to discuss their requirements so they can have the system that they really want.In business one has to speculate so free visit is not problem

Good luck and i hope you find an excellent installer who does fantastic job for you

As Happy has stated there are numerous options available too you, I would take Agiles advise with a pinch of salt with regards paying for a quote. He lives on another planet to most RGi on here and is not busy at 12.15pm on a Friday afternoon. I wonder why.
Go for recomendations, take your time, dont get baffled, ask as many questions as you need. Its your hard earned money being invested, so don't make an impulse purchase.
