Hi everyone

We have a 1920s villa that we’ve insulated and double glazed. We are now considering a central heating system. We have narrowed it down to a ducted gas system (brevis) or radiators.

We love radiators but the quote has come in $5k higher that the ducted gas system.

My question is how do I work out what the difference in running cost might be between the tow?

Given the initial price difference we are probably going to go for the deducted system.

Thanks

We went with ducted as well due to difference in price, radiators take a lot of wall space as well. Never could work out the running cost differences between the products would be interested to know as well

We also like the zoning that can be added to the ducted system. What ducted system did you go for and how are you finding it? We’ve got a heat pump on our main living area but want a whole home heating solution

Thanks

where in the country are you? if it gets hot in the summer why not consider a ducted heat pump? gives you the best of both worlds and is cheap to run

Can the suppliers give you case studies of local installations they have done?

I'm in Wellington and we used our air conditioners a LOT last summer. We heat for about 8 months of the year, cool for two months, and have two months where the temperature's ok. I find cooling uses less power than heating though, because it's not that hot.

We ended up with braemer in the end , definitely zone it especially if you have kids so it’s warmer in the lounge and not as hot in the bedrooms otherwise too hot to sleep. We went for two controllers as well one in the bathroom one in the kitchen. We have vent in the bathroom under the towel ladder so keeps bathroom warm and drys the towels. It does get really hot where we are in Upper Hutt so are looking at adding the cooling function as well. The units are quite noisy when they start up and run so think about where you would put the outside unit. We looked at heat pumps but as much as they have improved you still get performance issues with cold temps it gets to -4 here sometimes in winter so felt gas is a better overall performer. Cost on average is 200 per month over a year we don’t have double glazing so would be cheaper with double glazing.
