What it is
The Ideal 174863 is an automatic air vent designed for the solar side of an Ideal solar thermal installation. It continuously releases air that collects in the sealed circuit, so the collector loop keeps circulating without air locks. It is an Ideal-manufactured spare and is listed against the Ideal solar pack and Thermstore range.
Signs this part needs replacing
- Air continues to collect in the solar circuit despite repeated manual venting
- The collector loop runs hot at the panel but the cylinder does not heat as expected
- Pump noise or reduced flow through the solar primary circuit
- Weeping or dripping from the vent body or its cap
- Visible corrosion or scale around the vent connection
