Heat Pump Installation in East Auckland
The east is brick-and-tile, big windows and water on three sides. Sizing here is as much about keeping summer out as getting winter warm.
East Auckland runs from the older brick-and-tile of Pakuranga and Howick out to the newer builds around Botany, with the Tamaki estuary and the Gulf never far away. Two things shape the job here more than anywhere else in the city: houses built with a lot of north and west facing glass, and air coming off salt water. Both change which unit gets specified.
Brick-and-tile and a wall of glass
Pakuranga, Howick and much of Half Moon Bay went up between the late 1960s and the 1990s: brick veneer, tile roof, low-to-medium stud, and living areas designed around a big north-facing window onto the back lawn. It is a pleasant way to live and it is a real heat load in both directions.
In July that glazing loses heat fast after dark. In February it turns the lounge into a glasshouse by three in the afternoon. So on these homes the unit gets sized for the cooling load as well as the heating one, which often means a slightly larger unit than the floor area alone suggests.
The brick itself is not the problem people expect. The cavity behind it is usually uninsulated, but the mass holds temperature reasonably once you get it there, which rewards running the unit steadily rather than in bursts.
Estuary and gulf air
Half Moon Bay, the Bucklands Beach side and the lower parts of Panmure sit on salt water. It is gentler than an open west coast beach, but it is still salt, and it still works on an outdoor unit's aluminium fins over the years.
Anywhere with a view of the water, or a regular onshore breeze off the estuary, is worth treating as coastal: a corrosion-resistant outdoor unit, decent brackets, and a position that is not taking the wind straight off the water. Further inland at Botany and Ellerslie it stops mattering and a standard unit is fine.
If you are near the water, a gentle freshwater rinse of the outdoor coil a few times a year does more for its lifespan than anything else you can do. Your installer will show you where and how, and regular heat pump servicing catches fin corrosion while it is still cosmetic.
Newer builds at Botany and the open-plan question
Botany and the Flat Bush edge are much newer: insulated, double glazed in places, and built open plan with the kitchen, dining and living all one volume under a raked ceiling. One high-wall unit at one end of that space heats one end of it.
The unit reads the temperature at its own return air sensor, decides the job is done, and shuts down while the far corner is still cool. A properly sized unit for the living volume plus smaller heads for the bedrooms, or a ducted system where the roof space allows, gives an even result instead.
Which one suits depends on the truss layout and the budget. The heat pump installation cost page sets out the ranges, and the sizing calculator gives you a starting point before anyone visits.
Panmure, Ellerslie and the older stock
Panmure and parts of Ellerslie are a different mix again: post-war state housing, small weatherboard units, and an increasing number of new townhouses squeezed onto the same sections under intensification.
The older places are the ones that get cold and damp, with uninsulated walls and a single-glazed living room facing the wrong way. They are also the ones where one well-placed unit in the main living area makes the biggest difference to how the house feels, so they are worth doing even on a tight budget.
The new townhouses are the opposite problem: tight, well insulated, and easy to overheat upstairs in summer. They usually need less capacity than owners expect, and the money is better spent getting the position right than on a bigger unit. The heat pump installation page covers how that gets decided on site.

Common questions about heat pumps in East Auckland
Will one heat pump do an open-plan Botany house?
Rarely on its own. One unit in a single large volume heats the end it is on and stops as soon as its own sensor is satisfied, leaving the far corner cool. A properly sized living area unit plus smaller bedroom heads, or ducted, gives an even result.
Do I need a coastal unit at Half Moon Bay?
If you can see the water or get a regular breeze off the estuary, yes, a corrosion-resistant outdoor unit is worth it. Further inland around Botany and Ellerslie it is not necessary and your money goes further on performance instead.
Why does my lounge overheat in summer when the heat pump is for winter?
Because a lot of east Auckland living rooms were built around big north and west facing glass. The same unit cools as well as heats, so the sizing accounts for that summer load too, which sometimes means a slightly larger unit than the floor area suggests.
Is a 1970s brick-and-tile house hard to heat?
Not especially, once you account for the glazing. The wall cavity is usually uninsulated so it loses heat steadily, but the brick holds temperature reasonably well, which suits running the unit at a steady low output rather than blasting it for an hour.
