This Hydronic Heating Combo Package is perfect for small heating loads with Domestic Hot Water.

Also, this Combo Package is perfect for Solar Hot Water Applications and our Indirect Storage Tank comes with extra side ports to bring in Solar Feeds with an additional heat exchanger.

Our Combo Package uses a stainless steel tank for two reasons.

First, the tank acts as a buffer tank and keeps the Takagi T-D2-IN from short cycling. This allows the Takagi to run more efficiently and last longer.

Second, the Stainless Steel Heat-Flo Tank will outlast steel tanks and with it's heating coil - the Domestic Hot Water and Heating Water never mix. This is called a closed-loop heating system. The Domestic Water comes from the tank - and the Heating Loop goes through the internal Heat Exchanger. Simple - Elegant - Economical!

Our Hydronic Heating Combo Package will give you up to 40,000 Btu for heating side at water tempertaures of 180 Degrees or lower. As for the Domestic Hot Water you will have 40 gallons of hot water and the Takagi T-D2-IN will recover with nearly 90,000 Btu's.
