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...
