Intergas Eco RF vs HRE

[hard-work]

With SS heat Xs you don't need any heat pads like with aluminium heat Xs. The Navien is so efficient as it has a secondary heat X inside the combustion chamber, which is dual-pass so the flue gases have more heat extracted raising efficiency.

What?

 

[hard-work]

Many have heat pads.

 

[Dan Robinson]

Have you got your shovel handy? Care to elucidate on your rather sweeping, vague and ultimately incorrect statement?

 

[bernardgreen]

Heat pads ?

Could be bits of thermal insulation.

EDIT come to think about it. I recall that some boilers have additional insulation when sold / installed in Holland but not when sold in the UK

 

[Dan Robinson]

He's just making schit up from the snippets he's found in Google. Heat exchanger has sod all to do with the requirement or not of heat pads, and I doubt he's referring to the insulation inserts used in the Dutch Eco RF boilers.

Means usually two.

No. A couple is 2. A few is 3 or more.

 

[hard-work]

three years then.

Once again Hard-On can't answer questions and goes off on a tangent.

That I do. Running a condensing boiler at a lower temp as possible increases efficiency. A high temp decreases it. Even plumbers know that.

Assessing the variables, that is more the heat exchanger designer and combustion engineers field. So, you would be better off with a stainless steel heat X (which are by nature less efficient) at a lower temp because these aluminium heat Xs (supposed to be more efficient) build up crud at lower temps, so have to be at an inefficient higher temp.

You do not understand, this post and others confirm it. Efficiency is heat out to the potential of fuel in. I'm going to take your advice and stop feeding the troll.

Hope you have a good weekend VC.


I might finish this off this evening once the boy has been sent to bed.

Will see how things go. Got a nice Saturday morning to myself so hangover be damned

Small but delectably potent.........

 

[Dan Robinson]

Have no idea how strong mine is.... Probably around 15%.....but, there's more than one of the blighters.

 

[vulcancontinental]

I MIGHT have some FX2 and I MIGHT be in Letchworth tomorrow. Will know about the first in morning second depends on customer and filling loop.

 

[Dan Robinson]

I'm at home all morning
