What to know about heat loss surveys in Portadown
In Portadown, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
A surveyor visits your Portadown home to measure each room, window and wall before any heat pump is sized. Design outdoor temperatures for Portadown and the wider County Armagh come from local cold-weather data, not a national average.
Every heat pump we quote starts with a room-by-room heat loss survey, free with installation enquiries and also available as a stand-alone report.
- Landlords comparing properties before deciding where to switch first
- Homeowners planning insulation or building work who want to know the effect on heat demand
- Self-builders and architects who need emitter and system sizes early
What's included
- Outdoor unit siting options and noise check
- Room-by-room heat loss calculation using the MCS method
- Recommended heat pump size and design flow temperature
- Hot water cylinder sizing for your household
- Electrical supply and network operator notes
Houses in Portadown built in different eras can need very different heat pump sizes, which is why each is calculated room by room.
Grants and rules for heat pumps in Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in Portadown.
Installing heat pumps has been zero-rated for VAT in Northern Ireland since 1 May 2023, in line with the rest of the UK, until 31 March 2027. Northern Ireland has its own permitted development rules and building regulations, and we confirm what applies to your Portadown property at survey.

Heat loss surveys in Portadown: questions
Do you cover Craigavon as well as Portadown?
Yes. We arrange surveys and installation in Craigavon, which is about 3 miles north-east of Portadown, and across County Armagh.
What size heat pump does a Portadown home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Portadown home.
How soon can you survey a home in Portadown?
Survey dates depend on how busy installers are in County Armagh. We offer the next available dates when you enquire and confirm them in writing.
Why can't you size the heat pump from my boiler?
Boilers are often much larger than a home's real heat loss, because they are sized for fast hot water and quick warm-ups. Matching a heat pump to the boiler's output usually means an oversized unit that costs more and switches on and off too often. A room-by-room calculation finds the actual heat demand, which is what the heat pump needs to meet.
What is a design flow temperature?
The design flow temperature is the temperature of the water sent to your radiators or underfloor heating on the coldest design day. Heat pumps are more efficient at lower flow temperatures, typically around 35–50°C. Choosing it is a balance: a lower figure improves efficiency but can mean larger radiators in some rooms, so the design shows both.
