Oil boiler replacement in Angus
Angus includes Dundee, Forfar, Arbroath, Montrose and the rural glens of Glenisla and Glen Clova. The coastal strip has a mix of tenements and modern housing, while the glens have isolated farmsteads on oil.
Key facts
- Angus spans coastal towns and some of the coldest inhabited glens in Scotland.
- Coastal properties benefit from milder winters, but the Angus glens are among the coldest in Scotland.
- Dundee is on the gas grid, but rural Angus and the glens are largely off-grid.
- The heat loss calculation must account for real local winter temperatures, not averages.
- Coastal salt exposure is a factor for outdoor unit placement near Arbroath and Montrose.

What types of housing are in Angus?
Dundee has a large stock of tenement flats and Victorian villas, many with solid walls. The coastal towns — Arbroath, Montrose, Carnoustie — have a mix of stone-built terraces, council estates and modern developments. Rural Angus has farmhouses and cottages, and the glens have isolated properties ranging from traditional stone cottages to modern build homes.
How many properties are off-gas in Angus?
Dundee is on the gas grid, as are parts of the coastal towns. However, rural Angus — particularly the areas around Forfar, Kirriemuir and the glens — is largely off-gas. Oil is common for farmhouses and rural properties. The further into the glens you go, the more reliant properties are on oil and LPG.
What insulation does a Angus property need for a heat pump?
Dundee tenements with solid walls need internal wall insulation for a heat pump to work well. Coastal properties may have cavity walls depending on age. Rural stone-built properties in Angus typically have solid walls and need insulation assessment. Loft insulation is usually present but may be below current standards in older properties.
Will my radiators need replacing in Angus?
Properties in the Angus glens have very high heat loss in winter due to altitude and exposure. Radiator upgrades are almost certain in these properties. Coastal properties with cavity walls and reasonable insulation may need fewer radiator changes. The heat loss calculation is the only way to know for certain.
How does the Angus winter affect a heat pump?
The Angus glens — Glenisla, Glen Clova, Glen Prosen — are among the coldest inhabited areas in Scotland, with temperatures regularly below -10°C in winter. Coastal Angus is much milder due to the North Sea influence. A heat pump serving a glen property must be sized for these conditions. A system sized for coastal Angus would be inadequate in Glen Clova.
