Noisy heat pumps face council crackdown

Tim de Souza of Whangarei has a great new purchase but he's not allowed to use it. The local council has banned him from turning it on. Tim bought a Fujitsu heat pump about 3 months ago but a neighbour complained about the noise it emitted and the Whangarei District Council checked it out and agreed it was too noisy.

The heat pump measures 50dBA at Tim's boundary; it's only allowed to be 45dBA and that limit drops to 35dBA overnight.

Fair Go went to see Tim and the heat pump was one of the quietest appliances in Tim's house. The toilet was louder, the phone, the garage door and we were talking at about 57dBA. Tim thinks the council noise regulations are very low. He doesn't want to upset his neighbour but he does want to use his heatpump.

The Whangarei District Council stands by its low noise rule in its district plan. The councils working with Tim to try to resolve the issue. This includes advising him of ways to reduce the noise. The fence between Tim and his neighbour could be made more noise resistant and failing that the councils looking at commissioning a design for an affordable sound shield that can be whipped up by a trades person. The council says this is the first time it's had a complaint about noise from heat pumps and it will take advice from other councils around the country that have experience in this area.

The local installer, Airmaster Airconditioning from Whangarei, is going to wrap Tim's compressor in lead wrap to try to dull the noise.

Fujitsu says: "The sound generated by Heat Pumps in general will vary depending on size. Sound levels of all reputable brands sold in New Zealand are similar. Fujitsu products are tested to the same standards and those results we list in our specifications and brochures. It is common sense that Heat Pumps will produce some noise as they contain a compressor and fan. Acceptable noise seems to be a very subjective and personal opinion and while we are aware of different requirements of different Councils, their limitations have not specially been an issue to date."

However heat pump noise appears to be an emerging issue around the country. Acoustic engineer Paul Rayner has been solving noise problems for 30 years. He says his company Noise Control Ltd gets about six complaints about heat pumps a month, whereas they used to get one every three months.

He advises people to think carefully about the placement of the outdoor unit and sound issues before the heat pump is installed, as heat pump noise problems are difficult and costly to solve once the unit is in place.

What you need to know:

Consider noise at a design stage and you will get a simpler and more cost effective result.

Ask your installer what the noise level is from the heat pump and if they are familiar with local noise regulations

Noise issues usually occur when the outdoor unit is sited very close to the boundary.

Make sure your installer's trade qualified to install air conditioning and heat pumps. They could even be members of IRHACE the institute of refrigeration heating and air conditioning engineers - the industry association.

    It's autumn/winter time again. And as we all know, it's the time when people get to use more often the hot water, heaters, electric blankets, etc. AND HERE COMES MERCURY ENERGY AGAIN!!!!! Definitely, in my opinion, they are ripping us off. Every year, before autumn and winter time, they give this "changes to your electricity pricing letter." EVERY YEAR! Is there no stopping this kind of robbery?
