HI. Last week at my grandparents house -a council house. The glow-worm back boiler failed the plumber came and said The new baxi combi condensing boilers are very good they have improved. He said this because in May the whole house is going to be refurbishedand a baxi boiler is going to be fitted. Do you think he is right?
If the model with a secondary condensing heat exchanger I wouldn't buy one. If the council give it then you have no option.
Which model? Most still have upward firing burners into twin exchangers, which is a recipe for corroded burners in a year or two. Certainly, a quick check on the Baxi website shows that the Combi 105HE is such a design.
However, the newer Baxi Platinum Cxx HE appears to be a more modern design, but I know little about it.

HE Plus appears to be an in between type model. It has a single heat exchanger, but appears to place the burner below it, which is not good. It has some useful features, such as a built in flow switch, so you don't need a room thermostat if you have 100% TRV coverage.
I don't know quite what to make of it, although the upward firing burner does not bode well.

If the burner is not affected by condensate then it is probably OK. It is well priced with a decent DHW flow rate and the integrated flow switch makes matters far better for installation on the CH side. Only modulation down to about 9 or 10 kW is poor.
Quality? Too early to say. The plus will be a success because of the ease of instalation, good price and highish flowrate.
But, the non-condensing 105e was a very reliable and good combi. A relative has one of these, the instant model with integral water vessel, and I am impressed. It keeps a steady temperature and near instanmt water too. They have a small bath, but I was impressed at how fast it filled it. They never noticed much difference in bath fill up from the old tank system to the
105e.
Are you sure? I thought Building Regs now insisted on a room stat to stop short cycling. It is also a non-optional tick box on a boiler's benchmark form. I may be wrong though?

What is it?!
For the love of Jesus man its a baxi combi he plus!
Lol
Perhaps his needle just got stuck. Someone give him a nudge?
That is the case.
They insist on a control interlock, to shut the boiler down when no heat is in demand. There are various ways of doing this. One stat in house is the least desirable.
Depends on the boiler.
Every day is a school day!
my needle got stuck lololooloolo
The Potterton Promax is similar with an integral flow switch too. This was the original ill-fated Baxi Barcelona with all the problems ironed out and renamed, with even a new 'maker;.
The boiler which impresses me is the Glow Worm. Just had a HXI 30kW one connected to a thermal store with a quick recovery coil. The boiler was on full 80C when heating from cold, with all its output being absorbed by the store. When the store gets near up to temp the boiler modulates down to its
5 kW output. The boiler remained on the whole time and never cycled on and off once. On it low setting you can't hear the fan at all. It also has sound deadening on the boiler panels too. A quiet boiler indeed. Small, powerful and simple. Designed by a Dutch company Glow Worm bought out, who were then bought out by Vaillant. A Vaillant underneath. A pity the Glow Worm manual is lacking. It say it can be fitted to a combined one pipe F&E pipe, yet no diagrams merely referring to BS 5449, which means a number of ways of doing it.
The whole Xi range of Glowworm boilers are very good, especially as they've now done away with that stupid cap on the codensate trap which always leaked. They are dead easy to commission. Funny you should mention their manuals, the Vaillant 'clone' of the HXi, namely the EcoMax Pro, has a manual which refers to sections that don't even exist (indeed a section relating to the commissioning and which damn buttons to press to get the boiler to fire at different rates)!!
