Heat Pump Installation in Napier Done Right

Heat pump installation in Napier means matching the unit to your room, siting the outdoor gear to cope with coastal salt air, and doing a clean, code-compliant fit. A well-sized pump in a 1930s plaster home beats a bigger one every time. We install across Napier and Hawke's Bay.

What a proper heat pump install looks like

The unit that heats your place well isn't the biggest or the cheapest. It's the one sized for your actual rooms. An oversized pump short-cycles, costs more to run and never quite settles the temperature. Undersized and it labours through a Hawke's Bay cold snap. We measure the room, look at your glazing and how the sun tracks, then pick from there.

Most Napier homes suit a high wall heat pump in the living area, which is the quickest, tidiest fit for a single room. If you're heating a whole house or want it hidden away, ducted heat pump systems are worth a look, though they cost more and need ceiling space. If you want to sense-check size yourself first, our heat pump sizing calculator gives you a rough starting point.

On the day we run the pipework neatly, seal the wall penetration properly so weather stays out, and test it before we leave. A tidy install matters more than the sticker price, because a rushed one is what leaks, rattles and underheats.

Siting the outdoor unit near the Napier coast

Salt air is the big one here. Homes in Ahuriri, Westshore and anywhere near the water get a constant salt load that eats away at outdoor units that aren't looked after. We site the outdoor unit out of the worst of the salt spray and prevailing wind where we can, keep it off the ground for airflow, and point you toward models built for coastal conditions.

Inland and on the valley floor the problem flips. Hard frosts sit on the plains overnight, so the pump needs the grunt and defrost cycle to handle cold mornings without giving up. A rinse-down every so often and a proper heat pump service keeps a coastal unit going for years rather than corroding early.

Installing into older Napier homes

A lot of the housing here is single-glazed 1930s plaster and post-war weatherboard, plenty of it in Marewa and Onekawa. These homes leak heat through the windows and often have little insulation, so the pump has to work harder than the brochure suggests. That's exactly why we size up from the real room, not a rule of thumb.

Plaster and older weatherboard also mean the wall build matters when we're drilling and mounting. We check what we're fixing into and route the pipe run so it looks clean outside, not slapped across the front of the house. Getting this right the first time is what stops another winter of a cold, damp room.

Supply and install, and what it costs

We do supply and install, so we source the unit and fit it as one job. That keeps the sizing, the model and the workmanship under one roof, and it's why we're happy to stand behind our own installs. What you pay depends on the unit, how far the pipe run is and whether it's a straightforward single-room fit or something bigger. We break down the installation cost so there are no surprises.

If money's tight, the Warmer Kiwi Homes grant covers a large share of the cost for eligible households, up to a set cap. You apply through EECA, not through us, so check your eligibility there. We install right across the region, so have a look at the areas we serve across Hawke's Bay to confirm we get to you.
