I did notice an error in the immergas brochure. It had 80/60 with eff 96/92 The Bosch had 80/60 eff 91 And then I was thinking the Bosch was less eff. Then I looked at the SIME and it was 80/50 eff 92/96 or something and realised that the higher eff must be at the lower temp and figured for only 1% diff the Bosch must be just as good. So yeah I think I'll go Bosch. I think they will have better after sales service because they have reps here but the other wholesalers are only pushing the best deals. Re: Hydronic Heating - Which Brand to Choose? 14Apr 30, 2014 11:09 pm Woops, just realised I forgot to ask what I came here for. Does anyone happen to know where I could download the manual for the Bosch thermostat? Model FR120 I think. Thanks in advance. Re: Hydronic Heating - Which Brand to Choose? 16May 04, 2014 7:31 pm Hope I'm not too late joining in. I haven't really got a brand preference but would stick with the specialty European brands ... we have a Baxie Luna. What i would totally insist on is a condensing boiler. Gas is about to go up in price along the same trajectory as electricity did... an condensing boiler will pay for itself in just a few winters Re: Hydronic Heating - Which Brand to Choose? 18May 05, 2014 3:01 pm ![]() I've been thrown into a tail spin and can get an Immergas condensing boiler cheaper than the Bosch. I'll be going that way Can I ask how much the boiler is???? Re: Hydronic Heating - Which Brand to Choose? 20Jul 23, 2014 9:12 pm Thought I should add a few Hydronic things to look at before someone starts laying the cash:- Check the valves they are supplying, are they European (German are best IMO). Are they thermostatic? (This should be a yes for efficiency, except for the valve in the same room as the wall thermostat - this should be manual and always open). As for piping, I didn't use PEX, but I cannot see why Rehau and similar shouldn't be a problem. I would forget any installer who is using push fit or o-ring style PEX as the seals will eventually deteriorate (that's what seals do). Is the boiler appropriately sized for the installation? Almost all boilers in Oz used to be around 30kW and installers just install these and still mainly do. For a smaller install, a boiler will only modulate so much (down to around 20%). For example, my install was 6 radiators, (can't remember output), and a 30kW is too inefficient (too big) for this and I went for the 18kW Bosch unit. (UK sells 10, 12, 15kW etc, but we're stuck with boilers that have been tested to AU regs). I've had no problems with the Bosch unit since new (2 yrs old). However, don't buy the Bosch 'programmer', its junk, I bought it then sold it. Get a Siemens or Honeywell, much more logical and better functioning... Does anyone have a suggestion for a good hydronic in slab heating speacialist who may be able to help me with an existing system and wether or not it may need a seperator… 0 5354 Currently renovating, and our main lounge is 5m x 10m, with a cathedral roof peaking at 6.5m high. Currently have tiles on concrete slab. Room is very hard to heat. I am… 0 5306 Thank you. That is really helpful. Once we get the place done and passed for OC we can upgrade in the future once we get back on our feet and not paying mortgage and rent. 4 6134 |
