Replace Hot Water Tank with a Combi Boiler - How much??

franglais_2

Pealy, I have now installed a thermostatic bath-shower mixer tap and it regulates the water temperature from my to my combi boiler system brilliantly! The pressure is high, though fully adjustable, and the temperature rock steady, whether set at a high or low setting. No problem if someone turns on a tap in the kitchen either.

In England these thermostatic units are expensive, Scewfix has then starting at £200! I picked mine up while in France for 43 Euros, and incorporate ceramic cartridges (no maintenance) rather than traditional washers. Typically, the only problem is, the french set do not suit the standard British bath fittings, where the holes are at 7inch centres. I had to adapt the holes in my bath to 150.

Au revoir!

Hi Pealy,

When done make sure you turn the immersion off as it eats electricity by the bucket load.

So long as your tank's well lagged the energy consumed by the immersion is only dependent on the water you use, not the time that it's switched on for.

If it's thermostatically controlled, jack, yes.

The water would boil if it wasn't.

we have just had a baxi 40 duetec installed.. and we are having problems getting good pressure. The system is fine when using 2 taps but when 3 and 4 are used the pressure drops predictably. My questions is how can i get around this... I have been told two things increase the mains to house pipe to 32mm... alot of work as we are quite a way from the road.. My thinking is to reconect the old cold water tank in the loft to feed the cold supply and leave the combi to do the hot water only.. I was going to put a timed valve on the cold tank so it fills during the night..to prevent pulling from the mains at the same time.. Please help

You can't, you have a finite resource any way you look at it.

There is somthing that needs to be mentioned: A combi works at a higher pressure than a ' traditional' system and often leads to leaks in the radiator valves so you need to allow to upgrade these as well.

In a family house,a stored hot water system will beat a combi hands down. Modern hot water cylinders have high recovery rates and id much rather have one than running off litres of warm water wastefully waiting for it to warm up in a combi. Think carefully before installing a combi.
