System Operation

Q: Can I use anti-freeze to protect the system?

A: Anti-freeze can be used with our boilers. We recommend using an anti-freeze designed for hydronic systems, formulated with inhibited propylene glycol, a non-toxic anti-freeze. A solution of up to 50% can be used. No compounds containing petroleum should ever be used in the heating system. Do not use automotive anti-freeze.
