Vaillant, Ideal, Worcester: 10 year warranties!

or go for intergas and have a boiler that doesnt have the parts that breakdown in a worcester

Heard there back up is shocking for warranty work. Worcester are out to the boiler and fix it within 24 hours, not that its needed very often.

Round here you get Joe Smith heating turn up a contractor who has drove down from somewhere 60 miles away. If you phone tonight he may get to you weds next week if your lucky.
I have slated Worcester many times before however you can't knock the back up .

I tried inter gas and basically got nowhere and the few i fitted i wasn't really that impressed felt a bit cheap tat .

I heard it was all contractors who don't always have the parts and have to wait for the manufacturer to send them out etc. Its the downside of a smaller company I guess.

Okay, so was pretty sold on a WB 30i but have since found out that the VOGUE has both stainless steel made exchangers, so the ridiculous water softener issue on the Logic+ can be circumvented. Only issue with the vogue is that the flow rate is a bit inbetween: my current boiler is 11.4@ 35 degrees,... the Vogue 26 is 10.4, the 32 is 13.1.

Genuinely, apart from cost, what's the downside to having an oversized boiler?? If I went for a Vogue, I feel it'd have to be the 32, but I have concerns that it's way oversized for a 2 bed/1 bath semi but I simply don't know what the disadvantages are apart from purchase cost, and two installers have simply said it's too big for what I need.

Any thought?! 🙁

The heating output will probably be the same on both the 26 and 32, its just the hot water that will be better. You will be fine with the 32

These are the stats. Understand the flow rate bit but not what the CH side actually means. Little help? 🙂

 

[newcastle phill]

Its the Kw modulation.
Basically the low and high energy output

 

[Blackspaven]

Thanks, but I don't know what that realistically/operationally means. Guess it's something that the lay person isn't meant to know so they don't dispute installers; sounds complicated.

With a combi the ch output is irrelevant really it's always going to be over sized. 2 bed semi will only be around 8-10kw heat loss so the max ch output will be turned down to suit. To size the combi simply measure your incoming mains water flow rate, multiply by 42 (desired temperature rise, 35 isn't enough) then divide by 14.29 = kw net output needed to heat your flow rate. This is so you don't buy a 40 kW but only have 8 lpm or a 24kw and have 15 lpm. I hope this is helpful.

 

[Blackspaven]

Thanks for the advice, but it's left me with a bit of confusion unless I'm not working the maths correctly: My flow rate is 13/14 lpm and the calculation gives a figure of around 40/41kw... but all the installers have been quoting for boilers WAY under that. Even the guy AT Worcester suggested just on the basis of the house the 30i which is only 24kw.

I must be missing summat, but thank you anyway.

 

[ShaunCorbs]

Combis you rate on hot water (within reason ) 30kw would be more than good enough unless you have rubbish flow rate , but then you wouldn't be having a combi fitted

 

[Blackspaven]

Okay, cool, thanks. Well, as I said, mine is 13/14 lpm so simply out of curiousity where does that stack up in the grand scheme of things in terms of what is a decent rate?

 

[ShaunCorbs]

An ideal flow rate would be 15-20 lpm

Many thanks. There's always been an issue with flow in this house, south east water think I'm at the end of a run so the last to be supplied, and had to get rid of an electric shower as it kept shutting down in the morning due to low pressure cos everyone else is showering! 😀

Still, fitted a mains thermo shower and never looked back.

Appreciate the help fella.
