I just dont understand?

[chirpychippy]

Hello People,

I am buying a Worcester 28cdi compact green star boiler, basically if I buy the boilert, the flue, and the Magna Clean rather than put it on my mate the plumbers account he will fit it.

I don't understand the thermostat need, our current Worcester 24cdi doesn't have a wireless thermostat, or one fixed to a wall, all the controls are on the boiler which is very accessible as will be the new one. My bug bear is forking out for a thermostat that I don't currently see the need for, somebody did mention building regs, but I can't see why, we have thermostats on each rad as well.

I just don't understand, could someone explain it to me please.

Building Regs now require a boiler to have interlock.

ie a method of switching the boiler off when temp is reached without causing unnecessary cycling.

Just get a stat, they're as cheap as chips

This thread has to be a wind up.

In laymans terms, it is a good idea to have a thermostat fitted to your boiler so that it helps you save wasting energy, i.e. if your house has reached desired warmth, there is no need to allow your boiler continue to heat more wasting energy. It would do so if you did not have this thermostat fitted, so by fitting one, this cuts your bills down and saves green house gasses (co2) and so you save on your heating bills.

By installing individual thermostatically controlled valves also known as TRV, you can control individual room temperature, so if for example you don't need too much heat in one room you can set your TRV to a lower setting, again this saves you energy, it is all to do with saving wasting energy. You will soon recuperate your money through saving through lower heating bills. Thermostat also helps in frequent boiler cycling, save on wear and tear, as most thermostats have a few degrees of hysteresis, i.e. if you set them to say 20 degrees, they will switch the boiler off when it detects 20 degrees and then not fire up again until the temperature has dropped down to say 18 degrees, so you have a 2 degrees of hysteresis. But you can set it to where you find it comfortable.

And indeed Building Regulations now stipulate that all new installations now require this.

And good luck with the Wooster ****ebox

 

[Agile]

Properly used, a room stat will save about 10% of the gas! That's about £100 a year!

A wired one costs about £15.

A cheap wireless stat about £70.

No contest is there?

Thank you very much Agile for your informative reply and to kidgreen61 all makes sense now, much appreciated.

But........., from the less informative "Slapper" "And good luck with your Wooster ****ebox" would you care to elaborate as I haven't bought it yet, obviously you have good reason to call it a ****ebox maybe you could offer a less ****ebox alternative.

In actual fact, what would the heating engineers of this planet recommend for a good boiler to heat a three bedroomed terraced house with 1 bathroom and a ****e freezing cold conservatory that no number of radiators would heat, if you please.

There's a lot of bias on the forum towards certain brands...I would on a wide range and there are few issues with Worcesters.

Worcesters have a reputation for being difficult to work on and that's especially true of the cheaper models...but if you have it serviced each year your installer can probably get a 7 year warranty on it.

If you're set on Worcester go for the CDI CLASSIC....it has a superior heat engine and is much easier to work on, and most of the boiler internals have been around for 10 years...ie. it's well proven.

If showers are the norm then the 29 CDi Classic will be fine.

Worcester are probably the best in terms of parts availability, parts cost, manufacturer backup etc.

 

[chirpychippy]

Not particularly set on Worcester it's just we've got old one and have always been told they are good. I spoke to another plumber last night and he recommended the Ideal Logic + Combi 30 to
35Kw having just installed one for one of my customers?????! What of you reckon on this make?

 

[gas112]

Worcester parts need to be readily available as they constantly break down ask yourself why does a manufacturer boast about having a good back up service .
You dont want to know that as it means they must be breaking down a lot to boast that they can get to you when it does
Parts cheap ? in relation to what i have always found worcester parts to be expensive in relation to others .
What worcester are good at is marketing

 

[Terry lambert]

The amount of broken down Worcesters that I go to where the client says, I thought they were meant to be good.

As your showing them the pin holed flow unit that has flooded they're house, or disintegrated flow regulator housing ( All made from quality plastic) or the fan that died because you turned the power off.

I might have to get a bigger van for spares

To be fair they should have a mini expansion vessel fitted, but never are

 

[Dan Robinson]

The company that makes the plastic hydro blocks also make them for other manufacturers. At least one I can think of has an expansion /shock arresting feature built in.

Penny pinching?

Or just shyte?

Oh, and the manuals are a flipping liability.

 

[Gasguru]

The older left hand hydroblocks occasionally pin hole...it doesn't flood your house as it's just a very fine spray. all the one's I've seen are 2005 -2010 models so a long time ago. The mini expansion vessel has nothing to do with it despite Worcesters claims, we have 1 bar pressure around here.

I've never had a fan fail due to the power being turned off, but it occasionally happens, so what it's got a 7 year warranty.

Most Worcester spares are lower cost than many other brands especially Vaillant.

Usual ignorant exaggerated claims made by many on here that do few boiler repairs. There's a lot of Worcester spares as theres a huge number of Worcesters out there...they have the majority share round here.

There are no decent boilers out there with great design, easy to work on, reasonable service/spares costs, manufacturer backup, spares availability..a boiler with that lot doesn't exist.

Forget about past history...Vaillant used to make great boilers but they have produced the worst models for several years. As I've said within a manufacturers range of boilers only some models may be any good.

Ideal have been one of the worst manufacturers...their latest models are better but the company is still a shambles and always having to re-finance...anyones guess as to their future.

 

[Terry lambert]

Can't argue with Gasguru, because when it comes to repairs he is ......as the name suggests.

flooded might be an exaggeration but certainly ive had a few water damaged to ceilings/ carpet etc

I can't help but post as I find, they do keep me busy around here.

Have you taken a job with WB Gg

a s***te freezing cold conservatory that no number of radiators would heat, if you please.

When will people learn that a conservatory is a summer time only room, might as well just put a rad on the outside of the house would be just as much use
