If anyone wants to know, I have a Rinnai 26 at my place and we can comfortably run 2 showers at once.
Unit is factory set to deliver water at 50C - so no tempering valve required.
( there is an function to increase the water temp by a few degrees - 4C from memory)
I've had the unit for almost 20 years - so I am a fan of them
The problem with 'Hometech's' recommendation to put a unit for each bathroom, is not necessary.
What is necessary is to have the ability to determine what the hot water requirements are for the home and what pipe sizes are required to deliver that hot water.
What 'Hometech' may not understand, is the gas supply requirements.
3 bathrooms - 3 x 26 continuous flow units = 600mJ/h
Gas boiler (24 kW boiler) = 100mJ/h
Gas cooktop = 40mJ/H
Gas log fire = 40mJ/h
Total = 780mJ/h
- Size the gas pipe with that load with an index run of ( say ) 30m
- Size the same gas pipe with a load of 380mj/h ( less 2 HWU's )
Take the cost saving for the labour, equipment & materials into consideration.
There are substantial savings there to allow for a secondary returns system if required.
(House isn't that big - eg. 24 kw boiler
Hope now Hometech understands where I am coming from.
