New Gas Boiler.

Planet X

In the process of getting one fitted soon. Current Potterton is about 23 years old and wouldn't be the most efficient.
Gas, so what's a reliable one with an A rating efficiency. Used for rads and heating water. Located in a shed outside. RGI guy mentioned Baxi, then again this is what he probably fits. Saw a Worcester in a local shop, owner said it was quiet good. Just looking around doing my homework first before I commit.

Thanks.

When you say heating rads and hot water are you looking for a combi boiler fitted , or have you got a cylinder fitted.
i like baxi boilers and find them reliable and are easy to work with , on the other hand worcester boilers are the mutts nuts .

Yeah, if you mean a water cylinder in the hot press then yes.
I'm assuming combi is for rads and hot water tank then?
I have an immersion heater for the cylinder also which at the moment isn't working. Element must be gone.


So, you think a Worcester boiler is very good then? Just saw one on display in a newly (about a year I reckon) opened heating supply shop in Stillorgan.

go for the bosch over the baxi - if your budget allows change out your cylinder for a bigger one fully insulated (. twin coil to future proof) for the extra investment it will pay you back in a few years . zone the water tank separately as well if you can

very knowledgable staff in stillorgan I use them myself regularly .

Sorry, but what do you mean by "zone the water tank seperately"?

Zoning is where you can just heat the water and the rads seperately. Ie not have to heat the rads as well when only want to heat the hot water.

It's common now to have three zones that can be contolled/heated individually.

Hot water,
Downstairs rads,
Upstairs Rads.

If your going for something like a Worcester check out Viessmann! super stuff.

Know a plumber in Dublin Council and he said any heating upgrades they are doing a Worcester is being fitted...

gdavis

viessmann still get my nod

Dont know if I'd read into that too much. I know a company doing boilers for DCC installing Glow-worms.

The OP seems to have no clue so he/is asking a question.

The posters answering are happy to tell what suits them .....

@the OP:

Get a heating engineer to plan your new heating system. Get a heating energy demand calculation done accordiing to EN12831.
Without knowing the demand no one can install a suitable boiler.

Try to get the boiler installed in the house, this is more energy efficient and less maintenance demanding.

I'm assuming combi is for rads and hot water tank then?
I have an immersion heater for the cylinder also which at the moment isn't working. Element must be gone.

Combi-boilers need no immersion tank, they deliver hot water on demand and heat the house as well. Throw away the immmersion heater and forget about it.
Check if your CH system incl. the DHW is suitable for a pressurised system.

Posters are giving advice on what they feel from try tried and tested experience are good boilers, exactly what the OP asked!

Op didn't ask for advice on a new heating system, just a reliable good boiler recommendation

As for what suits them, your throw-away comment on combi boilers doesn't stack up all the time as demand may exceed supply (number of people/bathrooms etc) , re-plumbing to suit it maybe expensive and out-weight or offset any benefit for years to come

Agreed the boiler in the house is a good idea, and if outdoors/garage/shed is the only option go for a boiler designed for this purpose as the manufacturer will have paid more attention to casing heat losses etc. (Vokera balcony and the like)

+1 on the Worchester Bosch (especially the CDI's), Viessmann, Intergas, al worth the extra few quid IMHO

A little off topic but if i was replacing the boiler with a Worchester or Viessmann and the cylinder plus 9 rads.

What would that cost roughly?? and to get heating controls is that extra or do they come with condensing boilers cheers.

anuprising

would really have to see it , size of rads cylinder etc

boiler ,zones , cylinder and rads ,4k at a guesstimation

Planet X

I've got 9 rads and the boiler is in a shed 2 metres from the back of the house.
But...........an electrician got it up and running today :D

Still interested in getting a new boiler over the next few weeks.
Why zoned? I just have it on in the morning for shower water, 3/4 people and towel rail for drying towels. Apart from that I'd be a "light" radiator user. Recently got an insert stove fitted and love the heat from that.
Is it that zoning heats water directly to the water cylinder in the hot press and doesn't heat all the rad pipes? Is this where the saving comes in? Is it significant, the saving?

Judging by the fashion in which you use your heating, you could be a while waiting before you would make your money back. It's hard to say with out seeing it, but boilers that are away from the house are usually harder and more expansive to zone.

yes its the most efficient way to operate the system - at the push of a button you can heat the water without the rads or time the water to heat separatly from the rads .time and temperature controllable independant of each other .

at least a 30% saving if you have an insulated cylinder

its really the way to go ,convienience and comfort with a cost effective system

I have a standing Potterton gas boiler for over 20 yrs and it hasn't really given me much trouble other than service and minor part replacements (though I was never fond of the cold air from the vent in wall). Over the years, I have become more aware of the efficiencies of newer boilers - mine is reckoned to be about 60%, while newer boilers apparently have up to 90%.
Also, it seems that standing boilers are rarely installed these days - the wall mounted ones are now the norm.
Recently, I discovered that some work has to be carried out on my flue and vent to make them compliant to current regs.
So, I'm wondering if now might be the time to go for a new boiler.
However, it seems that older boilers, like mine, are simple in design and that modern gas boilers would probably never give me the trouble-free performance that I've had with my present boiler. Also, with my present system, I have the simple option of heat-to-the-entire-system, or have hot water only, as required (gravity feed) - via a turn of a thermostat in hall.
I'm trying to decide if I should bite the bullet now and go for a new modern and more efficient gas boiler - or just get the necessary work done to my present system and hold on my old boiler.
I probably fancy the idea of updating to a new wall mounted unit with its greater efficiency (presuming installing it wouldn't wreck the house), but I am still wondering if I might regret later scrapping my less efficient but reliable old boiler for a modern but less durable new boiler. Any opinions welcome.

imo,if u pay a little extra for the better boilers,and if they are correctly installed then u will have little or no issues with them
