What size heat pump do you need in Hastings?

Enter the room size and how well it holds heat for a rough size. An installer confirms it when they measure up.

About 5 kW

A rule of thumb NZ installers use, for a room with a standard 2.4 m ceiling. High ceilings, big windows and open-plan spaces need more, so an installer should confirm it.

How to size a heat pump

What does a heat pump cost to install in Hastings?

A standard back-to-back install means the indoor unit goes on a wall with the outdoor unit directly behind it, joined by a short pipe run. That is the simple case, and it is what the price table assumes.

For a typical home, the small high-wall unit, about 2.5 kW, suits a bedroom or small room. The medium high-wall, about 5 kW, suits the lounge. The large high-wall, about 8 kW, suits open-plan living, and a ducted system covers the whole house.

Size the unit to the room rather than the house. The energy label shows heating at 7°C and 2°C outside and cooling at 35°C, so compare quotes on the same figures. Frosts can occur anywhere in New Zealand, and inland and southern towns see colder winters.

A guide to heat pump sizing goes room by room, and the national cost guide sits behind the price table.

What pushes a heat pump quote up or down in Hastings?

The unit is only part of the bill. Two quotes for the same model can land far apart because the install is different.

Under the Fair Trading Act a quote must not mislead, including over hidden costs. Ask for anything extra to be written on the quote before you accept it.

How do Hastings heat pump installers compare?

Thirteen say they fit heat pumps. Six say they fit ducted systems and 5 mention multi-room setups. Eight mention servicing and 4 mention repairs. Some also fit hot water heat pumps, and free quotes are worth asking for, since the install detail is where quotes differ.

Choosing between a ducted or high-wall system comes first, then whether you want single or multi-room. For more choice, Napier, 26 km away, has 19 installers, while Havelock North sits 8 km away.

How can Hastings homeowners pay for a heat pump?

Two say they offer finance, so ask how the payments work and what the total comes to before you sign anything.

One mentions Warmer Kiwi Homes, the EECA scheme that funds heat pumps for eligible owner-occupiers. Eligibility depends on holding a Community Services Card or a SuperGold Combo Card, or living in a qualifying area. The grants guide sets out how it works.

Under the Consumer Guarantees Act, where no price has been set, you pay only a reasonable price.

Heat pump cost questions in Hastings

What warranty should I check on a heat pump?

Three installers mention a warranty on their own websites. Ask what it covers, who honours a claim and what is excluded. A firm that is an authorised dealer for the brand may handle a claim itself, which saves you chasing the manufacturer.

What is a multi-room heat pump system?

A multi-room system runs more than one indoor unit from a single outdoor unit, so more than one room is heated from one spot. It suits a home where you want warmth in several rooms. Ask for every room to be listed on the quote so nothing is left out.

Do Hastings installers cover Clive and the suburbs?

Installers based in town work across Hastings and its suburbs, including Flaxmere, Mayfair, Longlands and Parkvale. If your address is outside town, such as Clive, say so when you book and check the quote covers the trip.

Who should do the electrical side of the install?

Ask who handles the wiring, and whether that is inside the quote or added on top. A registered electrician should do that part. Read who can install a heat pump before you book so you know what to ask.
