TIPS FOR upgrading your radiant heat
1. Hire a Radiant Heat Expert
A successful upgrade to your radiant heat system depends on finding an extremely knowledgeable expert to design and install your system. You should also have an energy calculation done for your home and request your utility company to do a heat loss evaluation.
2. Estimate Costs for Heater and Installation
The Noritz model CB-199 Combi Boiler we installed can be purchased online for about $2,200. Installation cost us an additional $2,000. If your heating system lacks manifolds and zone valves, you will also have to upgrade your plumbing, and your installation cost could soar to $10,000 or more.
3. Have Your Water Tested
Mineral deposits and hard water can damage your tankless heater. Request a water quality report from your utility company. Since our water contained significant amounts of calcium and magnesium we needed to invest in a $2,000 whole house water softener filtration system.
4. Consider a Circulation Pump for Large Homes
If you have a large home with bathrooms and sinks that are far away (e.g. second floor), add a circulation pump combined with a motion sensor to shorten the wait time for hot water.
5. Maintain the System
You will need to have your domestic hot water system flushed once a year.
