  • Boiler Installation Checklist +

    Tankless Size

    The first thing to know in having a tankless heater installed is to determine the size tankless heater or tankless heaters you need for your home. This step is important and will generally be decided by the number and style of showers that the home owner would like to have able to run at the same time. Tankless heaters are sized in gallon per minute (GPM) rather then gallons per hour so the sizing is based on more any given moment or simultaneous shower. In certain applications it is necessary to have more than one heater installed to meet the customers needs.


    Venting is one of the most critical points on tankless heater installation. Once you know the size and how many you can determine the venting by understanding the specifications of the tankless heater or tankless heaters which you have sized the job for. Two things are a must on every properly installed tankless heater; the first is that all tankless heaters require outside air for combustion intake and second all exhaust must be properly sized according to the manufacturer specification.

    Gas Piping

    The second most common short cut taken on tankless heater installation’s is not sizing the gas pipe correctly. This is typically the most physically demanding parts of a tankless heater installation however this is also critical for the tankless heater to operate correctly on high fire situations. You will find that on all our tankless installations the project manager and field installer will both alike review and make sure that the gas piping for the tankless heater is sized correctly and that your gas meter is also sized properly.

    Return or No Return

    In larger homes it is common that have more than 30 linear feet of plumbing pipe will benefit from a return system if there is not already a return system. A return system is a system that will provide “instant” hot water for those larger homes which the water heater is fair away from the points of use. In retro-fit application’s a return system can be installed in one of the following three ways; First if there is an existing return line then we can retro fit a proprietary return system which will respond exactly the way the existing return system was if not better. The second way would be to actually install a return line if access is available to do this then we could install the return system and you will have “instant” hot water to all points of use. The third is a unique system that utilizes the cold line to create a return system. The only downfall to this system is that the cold water at certain points will be wamer when first opened. The upside is that you will have hot water instantly and without having to open walls or run a dedicated return line.
