Tekmar now offers 2-zone and 3-zone pumps, and 3-zone and 5-zone valves. The newly added switching relays and zone valve controls are compatible with all low-voltage thermostats and offer a variety of benefits.

When I look at any replacement hydronic boiler project, my tenet is always to assume the existing system is installed improperly. I like to pretend I am a famous detective, such as Sherlock Holmes, and my job is to uncover the hidden mistakes.

All Laars commercial NeoTherm boilers now come with a large color touch screen as standard equipment.

The units come in white, black, silver and wood-grain faceplates.

I like working with the control techs in our industry. They have such a passion for their craft. If left alone, they will control or monitor everything that moves, slides, shakes or switches. However, I do rein them in a bit when controlling a hydronic heating system. Several hard limits and a couple danger zones should be heeded. Of course, these should be verified with the boiler manufacturer.

The tekmar Boiler Control 284 offers the ultimate level of flexibility in mixed boiler plant operation.
