Heating system assessment

higster

HI, I've a oil boiler and underfloor heating system with 2 manifolds. The house is 12 years old and boiler room is very warm all the time and thinking something going on that is burning away the oil. My question is "are there companies that would come do an assessment with recommendations on changes/set up etc" or is a matter of getting a "normal" plumber out (plumber who installed system has long left the country). Based in Limerick/Shannon area. Thanks

Re

There are many, however regrettably many won't solve your problem.

Is the boiler is working all the time?

If so then you need to look at the time and temperature controls.

1: Times and programmer settings

Some programmers have a few options after you have set the times for on off

typically they are like the items below

off- will stay off regardless of times

on or off - auto which is reflecting the times

so if showing off - auto, its waiting for the next on time and visa versa

on - 24 hrs which means it over rides the times and will stay on

The programmer must take precedent over the stats, except for a frost stat.

2 Temps

once u have sorted 1 and are in control of the above

you need to look at the stats: room/zone and DHW cylinder stats and see are they working/ wired correctly

I once saw a system with similar issues where there were multiple zones all controlled by zone valves wired through relays.

The relays were 11 pin, the design required 13 pin, so when one relay closed when heat was called for, the power got to all the rest.

So maybe the stats are wired incorrectly

Am not a plumber but the above is the basics: you need to solve the problem before calling anyone

Is your boiler room part of the house. Are the pipes in the boiler room insulated? Some pictures would help

Do you feel you are using more oil than you should? Do you hear the boiler firing when its not supposed to be?

As above check that the heating schedule is set correctly and that its not set to maintain a specific minimum temperature especially when the house feels warm enough.

Put up a photo of boiler, timer, zones, thermostats, radiator thermostats and you may get good advice here.

Also how do you heat hot water, do you have instant shower like Triton, or use just water from hot tank heated by oil or heated by electric immersion?

How well is house insulated is usually first and cheapest fix. 350mm of fibreglass in attic for starters.

The other possibility is a broken weather compensation sensor, or a broken frost sensor
