Heating system installationToday is a long-awaited day: heating is being installed in my chilly villa. Hurrah!
Lots of research has gone into choosing the right system, and for anyone contemplating heating their home I'd strongly recommend that you join the
Consumer Society to access their online reports on different heating systems. It could save you from making a very costly mistake.
A number of friends have had HRV or DVS systems put in: these raise the temperature by about two degrees, but their primary purpose is to remove the moisture. Humidity is a real problem in the damp Auckland climate, and it's not unusual for clothes, bags and even shoes to turn mouldy. My friends are really pleased with the system, but personally I wanted something with greater heating ability... hey, I'm from Europe, where we heat our houses, and I've found it quite miserable living in a cold house. It's quite common in winter to step outside and for it to be warmer outside than inside!
Our choice was a ducted heat pump system: this is where a heat pump is hidden out of sight and the heat delivered through air ducts in the rooms. In total there are seven such air ducts throughout the house (with two in the larger rooms) and also three air return grilles, as the air circulates. So as well as heating the house, it'll also get rid of the moisture. And dust too, apparently.
Why did we choose a ducted heat pump system?- Our villa has very high ceilings, and has heat rises, so it made sense for the hot air to enter through the floor, rather than at a higher level.
- The ducted system is visually less intrusive: we didn't want ugly units on our walls.
- Less of a sensation of "being blown at".
- Ability to heat the entire house rather than just a room or two.
- Heat pumps are very cost-efficient to run compared to other heating systems.
What's important is that you end up with the system that's right for you and right for your home.
Choosing a supplierIn total four suppliers came to quote, and the quality of their knowledge and experience varied greatly. I'd strongly recommend that you get a number of people in to quote and you'll soon spot who knows their stuff and who's bluffing. Heat pumps are still relatively new in New Zealand, but really growing in popularity, so there are plenty of companies out there installing them to cash in but without the experience or knowledge. So it's quite likely that they'll recommend an installation that suits them, rather than you.
In the end we chose
Climate Control, who've been in the industry for a long time and really knew their stuff. They supply Daikin heat pumps, who are the industry leaders. Plus the sales consultant from Climate Control was the only one who didn't patronise me with "ohhhh, a ducted system is soooo expensive..."!
