Rated 5 out of 5 by from works great! This has been in the central heating system of our house in one of the coldest areas Englands for 13 years and the house is often empty for weeks on the winter. Never had any frost problems even with sustained -20C. If your house is sometimes empty in the winter, get it!

Rated 5 out of 5 by from Cost affective Just fitted home made solar hot water panels last summer. After seeing what "Specialist suppliers" were charging for solar fluid/antifreeze I thought I’d give this a go. After the worst winter for years, no problems. Good stuff. If it works in solar panels I would think it perfect for holiday homes Ect, no need to drain down the heating ,or keep it ticking over.

Use in vintage car radiators

Can it be used as an antifreeze in a vintage car radiator system that works totally satisfactorily by the "thermosyphon" method. ie. Does not have a water pump but is circulated solely by heat differentiation in the system.
Asked by: jimt
Hello Jimt. The Alphi-11 5ltr will work for this application. Hope this helps.

How much do I need?

I have a 3 bedroom bungalow with 8 radiators (largest 600 x 1100 double) heated with combi boiler. How many 5l containers will I need?
Asked by: ChrisCot
Hello ChrisCot. At the minimum recommended dose rate (25%), roughly calculating that your system contains 100 litres, 5 of the Alphi-11 5 litre would be sufficient.
