WHITE PAPER


Slashing Energy Waste with Smart Boiler Controls


Energy waste in older hydronic and steam systems is easy to overlook—yet extremely costly across multifamily portfolios. Get a clear look at why legacy boiler controls drive excess fuel use, how adaptive smart controls uncover hidden inefficiencies, and what property teams can do to improve performance without disruptive equipment upgrades. Gain practical insights to reduce operating costs, enhance comfort, and support compliance across every building you manage.

Top 5 Ways tekmar Boiler Control Systems Save Time, Energy, and Effort

Wireless Functionality Offers Install Flexibility

Avoid cutting and fishing wires through walls—making installations faster, cleaner, and far less disruptive, especially in dense brick buildings.

Compatible with Any Brand of Boiler

tekmar boiler control systems are brand agnostic, allowing users to control virtually any boiler brand which simplifies system design and gives owners long-term flexibility as equipment changes over time.

Nexa Connectivity Included

With built-in Nexa connectivity, property managers and contractors gain complete system insight, enabling wireless monitoring and control from anywhere on any device free of charge — avoiding vendor lock-in.

Setup and Commissioning Wizards

Setup and commissioning wizards guide contractors through configuration step by step, making it easy to get tekmar systems up and running quickly with minimal time, effort, or guesswork.

Stay Compliant with Local Emissions Laws

tekmar controls with wireless mesh sensors help customers reduce greenhouse gasses and stay compliant with local emissions laws by using real-time temperature sensing, smart boiler controls, and remote monitoring to optimize heating performance, reduce energy use, and simplify compliance reporting.

CASE STUDY

Smarter Boiler Management Across Multiple Buildings

tekmar-smart-boiler-controls-case-study

Customer Snapshot


Market: Multi-Family Housing

Application: Residential Heating

System Type: Boiler Control

Challenge: Difficulty managing several boilers across multiple properties

The Challenge

The Kelson Group manages 45 buildings across British Columbia. Traveling between sites to inspect and service boilers consumed significant time, and responding to boiler-related service calls that could have been handled remotely only added to the challenge.

The Solution

The group equipped their buildings with the tekmar Smart Boiler Control 294, giving them access to real-time remote monitoring of boiler operations, remote settings adjustment, and push notifications in the event of an issue.

The Results

Insight into all boiler operations across properties
Remote settings adjustments to help limit callbacks
Capture issues with heating system before tenants are negatively affected

“I really like the advantage of being able to make adjustments to the boilers on my way to the building and have it adjusted by the time I get there.”- Keith Newton, The Kelson Group
