Two-tiered chauffe-eau

[CeeJay]

Is there such a beast as a two-tiered chauffe-eau, with one small tank and another larger one which could be brought into action when greater demand warrants it?

Why not connect two in series?, a small one fed with cold water by a larger one. When you only need a small ammount of hot water just switch on the smaller one, when you need lots of hot water switch on the large one as well, that will then feed the hot water through to the smaller one, they are quite cheap and not difficult to fit.

You can use a duel emmersion hws cylinder,use the top emmersion heater when on low demand etc.Why waste money on two tanks.happy plumbing.

These things are so well insulated that, if they are running on off-peak electricity, they use so little juice that it's probably not worthwhile messing around with hybrid two-tank arrangements.

Now if its a question of piping hot water long distances to remote parts of the property where you would waste lots of energy waiting for the hot stuff to arrive, then it may be worthwhile having two discrete systems.

I've just discovered a water heater in a roof space that has been left on for the last year (full of water, but never used and the house is on a central heating boiler) - must have wasted quite a bit on money !!

I'm trying to get a plumber to fit an instant heat boiler for hot water rather than keep a tank full hot the whole time. Before I moved out to France, for the previous 20 years in my house(s) in the UK I always had instant heat boilers for hot water (actually combi-boilers that did the central heating as well) and they were great.

They don't take long to get to heat (I never noticed a delay in the hot water coming through), you have unlimited hot water (the tank never runs-out) and they only heat the water you are going to use there and then (no heat loss from a hot water tank.

Problem I'm having is to actually get a plumber to come round to quote. I don't like to hassle them too much (in case this annoys them), but at the same time, if you don't pester a bit, then you never get anything done. Is this a general problem is France or just in my area (or just me).
