Heat pump installation in Grasmere
Grasmere and Prestonville still lean on wood more than most of Invercargill, and they’re inside the airshed, where older burners are on a deadline. Mahdi and our heat pump installer swap the burner’s job over to a heat pump, sized to the room it used to heat.

Out: Old wood burnerIn: a heat pump sized to the room
In the Invercargill airshed, wood burners put in before September 2005 can’t be used any more, and non-compliant ones from 2005 to 2010 must stop by 1 January 2030.

Mahdi and our heat pump installer do every job together: the unit, the pipe run and the wiring. At the quote visit, Mahdi looks at the room, where the outdoor unit can go and your switchboard’s capacity, then quotes.
About Mahdi and the teamWhat we do in Grasmere
A burner that heats the living room and the hallway is a lot to replace with one small unit, so Mahdi sizes the heat pump on the room and how open it is to the rest of the house. Where the burner warmed the bedrooms too, a multi-room system takes over.
Prestonville’s workshops and offices get the same team: the heat pump and the electrical side quoted together.
On the quote visit Mahdi looks at the burner, the room it heats and the doors between it and the rest of the house, then sizes the heat pump to carry the same load. The outdoor unit goes up off the ground on a pad or brackets.
Grasmere’s burners and the frost
Inside the Invercargill airshed, a wood burner put in before September 2005 can’t be used any more, and a non-compliant one from 2005 to 2010 must stop by 1 January 2030. With more burners here than in most of the city, plenty of Grasmere homes are working out what comes next.
Grasmere is flat and low beside the Waihopai River, behind the flood banks built after the 1984 flood. Frost forms most readily on flat ground where cold air can’t drain away on a calm night, so a heat pump on a timer earns its keep here.
A heat pump in place of the burner also means no more firewood to buy and dry before winter, and nothing to time against the airshed dates.

Mahdi comes out and quotes
He looks at the room, where the outdoor unit can go and your switchboard’s capacity for the new circuit, then quotes the heat pump and the wiring together.
Install day
Mahdi and our heat pump installer take the old unit down if there is one, put the new indoor unit up, set the outdoor unit and run the pipes, and Mahdi wires it in from the switchboard.
Warm and handed over
We run it on heat, set the timer with you and show you the filter: a clean once a month through winter keeps it working well.

Tips for Grasmere homes
- Find out when your burner went in: the date decides whether it can still be used.
- Measure the room the burner heats, and note the doors that stay open to it.
- Set the heat pump’s timer to come on before you get up on frosty mornings.
- Note which rooms go cold first when the burner dies down at night: they’re the ones to plan for.
Grasmere questions
How do I find out when my burner went in?
The council’s building consents team holds the date. Send Mahdi a photo of the burner as well: it helps him size the heat pump that replaces it.
Will one heat pump do the burner’s job?
For the living room, a high-wall unit sized to the room does. If the burner warmed the hallway and bedrooms too, a multi-room system takes that on.
Do you put heat pumps into Prestonville workshops?
Yes. Mahdi quotes the heat pump and the electrical side together, and we work round your hours.
We also put heat pumps in nearby in Waikiwi, Gladstone and Otatara. All areas
