Hi Guys….
There is a similar post, but I do not want to highjack it. Hope you do not think this is stupid. I am looking to replace my gas boiler for my hydronic heating (panels) I live in middle of NSW and it gets cold. I am looking at Skyline Engineering (who are excellent), Tivok and Stiebel Eltron. I have the following problems:
1. One installer will not explain how he calculated the Heat Load. I tried to backwards calculate this on excel, but he did not even use my exact room calculations and he will not explain. Saying it is far to complex. His room volume calculation does not even match mine. So is there an excel spread sheet for head load calculations.
2. I know cost of the equipment – lots.
3. I know the cost of my electricity
4. I do NOT know the cost of heat pump running.
5. The installers will not give me a running cost for the unit(s). Saying there are far too many variables. But it will be cheaper than gas…. but how much….
6. Yes, there are variables, but if I cannot compare apples with apples, how can I compare the cost of gas and the cost of a heat pump. Plus, the wife is not as excited about this as much as I …good. But I need to know
Any help would be gratefully accepted. Thank you. The forum is great.
