Wood Boiler Installation Wood Boiler Installation

Installing a wood boiler outside entails moderate to advanced do-it-yourself skills. It is advised that you seek the help of a professional if you should run into any problems during the installation process.

Pouring a Concrete Slab or Foundation

You will need to pour a concrete slab to create a base for the wood boiler as well as provide a place to put the wood. The concrete stand should be poured about 4 inches thick to provide a good base for the wood boiler. You can also consider setting down concrete blocks instead of pouring the slab to provide the same base for the wood boiler. You need to make sure that the slab or foundation for the wood boiler is level and stable before installing the boiler.

Dig a Drainage Trench

You will also need to dig a drainage trench for the water boiler. If you rent a back hoe or perform this task manually you will save the cost of hiring a landscaper or septic tank installer. PEX piping will be placed in the trench, connecting to the boiler and running away from the house. The PEX piping should either be insulated or you can purchase insulating material yourself to place in the pipes. Place twine or a string line in the piping in case you need to make repairs later on that require you to remove the PEX from the trench.

Installing the Heat Exchangers

The next part of the wood boiler installation is the installation of the heat exchangers. This part should be a water-to-water heat exchanger for your water boiler. There should be no problem finding the type that fits your boiler.

Connecting PEX Piping to the Furnace Connector

PEX piping will need to be connected at both the furnace connector and at the heat exchanger. Compression fittings are used for your connections, which eliminates the need and the cost associated with hiring a plumber. The fittings simply push into place for the connections. 

Installing a 15A Circuit for the Water Boiler

You will need to have a 15A circuit breaker installed in your home’s breaker box. This circuit is used to connect the 110V wire that feeds power from the box to the water boiler. This work should be done by a qualified electrician so do not skimp on this cost. It could be the difference between life and death if handled improperly.

Installing a Thermostat

A thermostat used to regulate heat for your water boiler needs to be installed. A 2-wire thermostat should be sufficient to regulate the circulation of hot air when needed. This will also allow your water boiler to operate automatically in times when you may not be able to do so manually, such as in the case of an emergency.
