horizontal thermal store

Tim Lamb · 2009-06-29T08:17:22+00:00

OK so it is probably a contradiction in terms but I have a *space* issue.I made a decision to use underfloor heating, thermal store, system boiler and the old garage as a kitchen diner for an annexe we are constructing. What I failed to realise is that *garages* are really too narrow to accept all the bits of tackle that housewives consider essential.One possible saving has been to consider fitting the thermal store in what will be a very modest (minuscule) loft. I don't have the actual dimensions yet. Browsing through various offerings looking for short/fat versions, I came across a horizontal store!How serious a problem would this cause? I vaguely remember stratification being discussed here. I have no current ambition to use any alternative energy source .regards

Until an explosion and no insurance claim.

Read on.....

BS-approved UDHW systems training manual, under the heading of maintenance, p40:

"the installer is responsible for the safe INSTALLATION of the unit. He/she must also make his customer aware that periodic checks of the equipment are ESSENTIAL FOR SAFETY... some manufacturers recommend a MAXIMUM of 12 months. Experience of local water conditions may indicate that MORE FREQUENT inspection is desirable."

BS6700: 1997 states that with unvented cylinders, the "maintenance and periodic easing of temperature relief valves is particularly important".

Too late all:-)

The *loft* floor has been fitted at the normal height so there really isn't space now for a store.

The long term plan for this building is to be part of an office suite (when I finally get round to sorting out the timber barn) so it might be possible to route the pipework for some future centralised ground source heat pump set up. Be a nice planning inducement, anyway:-)

Roughly 300 sq.m total floor area. Be a big collector array or a lot of pumped water!

Risks of explosion with an indirectly heated pressurised cylinder are to all intents nil anyway.

With an electrically heated one, the risks are greater, but still require the simultaneous failure of a number of protection mechanisms. Something it seems that many of the US examples you cite did not have.

Well that's fine. Inspect it yourself each year... especially if you are the installer.

In other news; brushing your teeth is worthwhile, report claims.
