Light Commercial Boiler Reviews

[tm plumbing]

I've been asked to quote for a replacement 50kw boiler in a welfare club & notice Vaillant and Viessmann do 46kw & 45kw models respectively. Has anyone fitted any of these sizes & any reviews much appreciated.
Thanks

Viessmann commercial are horrible. Worcester Bosch have taken over Buderus and rebadged the GB162. Lovely boiler. Gets my vote every time.

On a similar note ferroli are sneaking out commercials under the Lamborghini badge. Give them a steer too.

Thanks, I did look at the 162 but thought min was 65kw

Why one large TM? Can't you go for two 26kW on a LLH ?

Should still be able to get it of a U6 a John ? as its only light com LOL

No reason Chris I've not seen existing setup yet so keeping an open mind, two might work better depending on how they use it & their HW demands. I've not fitted a lot of 40+kW so was just looking for reviews. I did fit a Keston a few years back in a church but believe they are high maintenance. If it's the one big one it's looking like the Vaillant but I'll call my Worcester rep for a heads up too that's if I get the job ;-)

Two logics systems on a LLH or two heat only on a cascade. If it's a cascade make sure u have good filtration .

Anyone would think I worked for Remeha but I think the Quinta pro 65kw would serve you we'll. nice compact wall mounted. 900 by 500by 500 mm.

I dont like the Quinta either. Too many bolts to undo.......

I don't mind the Quintas or the boulters, flavor of the moment would be a ATAG for me though. the do a 38 or a 51kW

Had a look at this the other day & 2 Worcester Cdi 30 kw with a low loss header looks the way forward. Also 2 250L cylinders. It has 3 heating zones plus HW.
My dilemma is whether to introduce pressure to the malleable iron or not.
Anyone used a low loss header on an open vent system as I've only ever seen them used on sealed systems.
