replacing and moving gas boiler

xgtdec

Hi there

Just looking for some advice on our home heating.

At the moment we have a 20 odd year old gloworm gas boiler in the kitchen and we want to replace it and also move the location of its replacement from the kitchen wall to the garage wall outside. My plumber explained that i couldnt get a grant from seai because i would have to zone the house which means taking up floors etc and he advised it just wasnt worth it!!
The proposed solution was that the moving of the boiler was no problem and the replacement would be a veismann boiler as he advised these were a solid brand. Instead of zoning trv's would be fitted to all rads which they do not currently have.
Could anyone advise as to reliability of a veismann boiler and possibily explain the whole zoning thing and if its worth considering converting to it?

Good solid boiler.
Zoning is always worth it as you will have both TIME & TEMPERTURE control over each zone. So you only heat the area of your home that you are using when you want to. If your house is 1,600sqft & you have it zoned, why would you want to heat bedrooms during the day? Zoned, you are only heating an 800sqft house.
With temperature control, if you have your heating on for, say 2 hours, if the house reaches 20C within 1 hour, the heating will switch off automatically, saving you fuel & thus money. Especially with HE boilers, they will heat your home far quicker than a standard efficiency boiler.

Thanks for that!!! very much appreciated, i think we're leaving it at unzoned, the work involved with floors coming up etc puts us off and as it is we cant find fault with the heating arrangements as is. Its nice to know the boiler choice is good!! Thanks for your reply!

Make sure your RGI plumber powerflushes your system before the new boiler goes in. It's a good days work doing this but without it your new boiler won't last very long

He should know but not necessarily. Hell have to use a machine and chemicals. No other way is satisfactory.

Ask him about a wireless room stat if you are no zoning, at least you will have temperature control over the space heating and stop the boiler from anit-cycling.

Viessmann do a wireless programmable room thermostat called a Vititrol 100.

what kinda buck are we talking for this boiler and controller ?

The OP doesn't say what output boiler the plumber is using. Or what model.

I think its a Vitodens 100W Nat/Lpg 26kW System 9424.

Also checked on the full chemical flush and yes its being done thankfully!!

OP I'd be all on for zoning the house while your plumber is in there.

For example in my house there's simply two quarter-turn valves, one for 'downstairs' and one for 'upstairs'. The hot water cylinder is on it's own thermostatic zone.

We (almost) only ever have either 'downstairs' or 'upstairs' on at any one time, as required. This saves heating unused parts of the house, and it's a very simple system - even the kids can use it.

Id be all on for it if we were going from scratch but having to take up floors etc is a turn off, plus the added cost, in the end we went for a single loop and trv's on all the rads which we'll adjust to suit, i think its the most cost effective solution without pulling the house apart!!
