Weil McLain Boiler Buyers Guide

For any HVAC appliance, we always recommend you choose a good contractor over the brand. That includes boiler systems. Boilers installations are done by a plumbing contractor or an HVAC contractor. It is crucial, especially for boiler installations, that the boiler is installed correctly. This means it needs to be sized correctly and the boiler piping needs to be sized and configured properly.

Furthermore, all the controls, expansion tank, and air elimination devices need to be inspected and replaced as necessary for boiler replacements. Near boiler piping and components are important. Finally, many aspects of the boiler system need to be looked at by a competent professional. This ensures proper operation when the new boiler is put into service.

Controls Available from Weil-McLain | For Enhanced Efficiency and Boiler Operation

Many times getting efficiency means optimized control. I know it’s more than that, but boiler control is an important factor in efficiency and saving energy. Weil-McLain has several different products available to enhance boiler operation and efficiency.

  • Boiler Sequencing Control - Controls more than one boiler (up to four) in an optimized sequence.
  • Circulator Zone Control(s) - For single or multiple zones (up to 6 zones).
  • Outdoor Reset Control - This control changes the setpoint of the boiler based on outside air temperature.
  • Zone Valve Controls - for optimized zone valve control.
  • Hydronic Multi-Stage Boiler Control - for lead/lag control of multiple boilers
  • Boiler Control Panels for optimized control and staging
  • Boiler Modulating Control offers modulating control for up to four boilers with lead/lag rotation, adjustable modulation start point, and outdoor reset control.

What is an Outdoor Reset Control?

An outdoor reset control is a device that changes the setpoint on your boiler based on the outside air temperature. It has been tested extensively and is a proven method of reducing energy consumption therefore saving on energy costs. In some regions, if you have an outdoor reset control, you qualify for energy and tax credits/rebates.

Boiler Control Features and Additional Products

For Weil-McLain Boiler Reviews we typically include just boilers. However, Weil-McLain also manufacturers baseboards, indirect-fired heaters, heat exchangers, and controls to support their boiler systems.

Furthermore, their boiler controls include a Boiler Sequencing Control for the firing of multiple boilers systems found in some light commercial applications including apartments, Outdoor Reset Controls for added efficiency in your boiler system, and Zone Controls Module for controlling several zones including zone valves and circulator pumps on a hot water boiler system.

Their Boiler Modulating Control is, in my opinion, an excellent extra feature to have for optimized control. It can control several boilers and rotate them in a lead/lag rotation schedule. It also has outdoor reset control built-in and lots of extra features designed for optimal control and efficiency.

In addition to the controls, Lastly, Weil-McLain also produces plate heat exchangers and swimming pool heat exchangers as an added attachment to a boiler loop for heating a swimming pool.

Warranties | Weil McLain Boiler Buyers Guide

Weil McLain offers industry-standard warranties for all their boiler models. It is important to understand most HVAC manufacturers offer a limited parts warranty. That means you will have to pay for labor unless the warranty states otherwise. Always make sure to read the warranty and understand all the limitations and exclusions before making the purchase. Some warranties are not transferable.

Therefore, if you sell your home, the warranty will not transfer to the new owner. Additionally, other warranties have maintenance requirements. If you do not comply, then the warranty is void.

Furthermore, condensing heat exchangers need to be tough. The condensation from gas or oil byproducts is very corrosive and causes a heat exchanger failure. Most manufacturers offer extended warranties on their condensing systems for that reason.

These warranties usually are separate from the parts warranty and with 20-year to lifetime terms. Make sure to cover yourself with a proper boiler warranty. Finally, for the premium brands, check to see if an extended boiler part and labor warranty are available.
