Hydronic heating offers complete, energy-saving system for homeowners

When your customers are selecting home appliances, what priorities often drive their decision making? If the answer is cost, comfort, or environmental impact, they may be interested to learn more about hydronic systems, which offer efficient home and hot water heating simultaneously.

When it comes to hydronic heating, there are different options: the hydronic furnace and in-floor hydronic radiant heat, which is most commonly used for homes in cold climates.

Here’s an overview of how one of these systems works and how they can benefit both you and your customers.

What is a hydronic furnace?

Hydronic furnaces connect seamlessly to select tankless water heaters and condensing boilers to deliver efficient, simultaneous home heating and domestic hot water in one complete system. Hydronic furnaces use hot water from a tankless water heater, saving installation costs—and making traditional furnaces seem like a thing of the past. By pairing them with propane-powered water heater, contractors can help their customers enjoy steady, comfortable heat throughout their home.

A propane-powered tankless water heater supplies continuous hot water—unlike a traditional storage tank with a capacity of just 50 or 75 gallons and required time to recover between uses—so the system can pump a constant flow through the heating coil and deliver steady, comfortable heat to the home without the need for a fuel-powered furnace, gas piping or an extra exhaust vent to the atmosphere. At the same time, the tankless water heater performs its primary job without interruption, prioritizing heating the water that is piped to showers, sinks, dishwashers, and washing machines.

These systems can be installed in a new home or added to an existing home and can be paired with an air-source heat pump to maintain comfort and efficiencies—even on cold days when the heat pump can’t keep up. Plus, this does away with the super in-efficient resistant heat coil for the emergency heat mode.

How can this technology benefit my customers?

With a hydronic furnace, homeowners can rely on steady, comfortable heating throughout their home, saving space, energy, and money.

Budget-friendly

A tankless water heater is typically more expensive than a traditional storage tank model, but some manufacturers offer the hydronic air handler for less than a comparable gas-powered condensing furnace. When you combine that with installation savings you end up with a lower cost installed product. Plus, because propane-powered tankless water heaters only heat water when it’s needed, they can help homeowners save more than $150 per year in energy costs when compared with typical electric storage tank water heaters.

Increased comfort and control

Comfort is one of the biggest perks of hydronic heating. In fact, many homeowners report that their heat is less dry than heat radiated via a traditional furnace. With a hydronic furnace, homeowners control the air temperature by setting a thermostat, just as they would with a traditional furnace or heat pump.

Sustainable operation

And for environmentally conscious homeowner customers, they can have peace of mind knowing their system is reducing emissions compared with other energy options. Notably, a propane tankless water heater produces roughly half of the carbon emissions of an electric storage tank system when full lifecycle emissions are taken into consideration. Plus, they’re aiding in water conservation efforts because hydronic systems create no wastewater. Instead, they take the water used to heat the air and recirculate it through the tankless water heater.

How can installing hydronic heating benefit my business? 

The benefits of hydronic heating don’t stop with the customer. Plumbing and HVAC contractors can reap the benefits, too. The dual technology presents an opportunity for some plumbers to get into the heating business and some mechanical contractors to add tankless water heater installation to their line of services.

Some industry pros predict that builders will embrace hydronic heating as homebuyers already familiar with the benefits of energy- efficient tankless water heaters learn that those energy- and water-saving devices can also help heat their homes.

Residential water heaters are often taken for granted. They’re usually installed in a closet or basement or other out-of-the-way spot, and it generally costs less to replace a standard water tank system than other home systems, so many homeowners don’t see water heater maintenance as an urgent priority.

But proper maintenance almost always pays off in the long run, and not just for homeowners. While contractors may benefit from the additional business generated by emergency service calls, those one-time sales aren’t nearly as important as the name recognition and trust they can cultivate with maintenance agreements that help insure optimal product performance and longevity.

Unfortunately, many water heater service professionals either don’t recognize the value of maintenance plans, or don’t know how to effectively communicate the advantages to their customers.

Pay a little now or a lot later

Over the life of an appliance, the minor cost of an annual inspection or tune-up can help save homeowners in multiple ways. Inspections can catch small issues before they become major problems, which in turn helps extend the life of the water heater. In addition, regular service helps ensure efficient performance, which can reduce energy costs and provide for consistent product performance.

Preventive maintenance also helps protect homeowners from the inconvenience and high costs associated with emergency service. Unplanned repairs tend to cost more than regular maintenance and can interrupt household routines, which can be more than a nuisance. Missed work and the disruption of planned events like family vacations can add to the financial burden of emergency water heater repair.

Many successful contractors recognize that it’s in their own interest to help customers avoid emergencies, no matter how lucrative they can be. Routine service calls don’t generate a lot of income, but they build name recognition and, more importantly, lasting relationships. That can be a vital distinction when it’s time to replace an existing water heater, or in the unfortunate event of an emergency.

Maintenance vs. warranty

One misconception that contributes significantly to deferred maintenance is not having a full understanding of a manufacturer’s warranty. Many homeowners assume that the warranty will cover most repairs. Why pay for even minor service now if you expect your warranty to cover the cost of major repairs later?

But the scope of a warranty is limited and very specific, covering demonstrable defects in manufacturing. Proper installation and application and, in some cases, even documentation that the recommended maintenance has been performed, are typically required in order to maintain a valid warranty. Even then, warranties typically don’t apply to local conditions that can significantly affect water heater performance, like water quality, climate, air quality and the hardness of the water supply.

A warranty is an important tool that homeowners should be familiar with. But the best warranty will not apply to the simple wear and tear of daily use or issues arising from local adverse conditions.

Connect with homeowners

It doesn’t take salesmanship in order to maximize the long-term advantages of maintenance agreements. In many cases, a few simple tweaks to existing workflows can be extraordinarily effective tools to open new opportunities for preventive maintenance.

One simple enhancement is to follow the example of HVAC contractors and leverage seasonality. If water heater use tends to go up in your service area during colder months, try to schedule new maintenance service calls in late summer or fall. Employ multiple seasonal opportunities to connect with customers, from back to school, winter holidays, summer vacation or the switch to Daylight Savings Time, and set up regular seasonal reminders for follow-ups.

The single best time for a maintenance agreement conversation is immediately after a substantial repair or emergency service. Homeowners who have recently experienced the cost and disruption of a major equipment repair or unplanned replacement are in a position to recognize the likely payoff of an investment in ongoing service.

Ultimately, communication is the most crucial tool for connecting with customers about preventive maintenance service. Contractors who can effectively and objectively relay information to homeowners are in a position to relieve the anxiety many of them feel about water heaters and other large home appliances. By educating them and offering a convenient, affordable solution, you can establish your company as the trusted solution for any foreseeable service.

Providing ease, cost savings and strong performance, product offers contractors a competitive advantage 

To provide a quick and easy tank replacement solution to both contractors and end users, Rinnai America Corporation created the non-condensing Demand Duo® R-Series Commercial Hybrid Water Heating System. Its design connects easily to the existing 6” B-Vent, allowing Contractors to quickly and easily replace standard-efficiency atmospheric tanks. The end user, too, can benefit by simply upgrading to a “best of both” system, featuring part-tank and part-tankless design.

“With patented technology, the Demand Duo R-Series delivers superior, reliable performance and a longer service life,” said Dale Schmitz, Marketing Segment Manager. “Switching from traditional tanks to the consistency and efficiency of the Demand Duo R-Series is simple and benefits customers with a lower total cost of ownership.”

Sold in 80 or 119- gallon tank options, the Demand Duo R-Series eliminates the need for new vent penetrations. The pre-installed drip leg and 36” Swivel-Flex Gas Line also creates material efficiencies and reduces install time with a pre-installed electrical junction box and duplex outlet. The digital controller, which comes with the product, also allows management of building recirculation without having to purchase an additional aquastat.

“With cost advantages to the end user, as well as ease of installation, this product gives contractors a great competitive advantage,” said Schmitz. “Rinnai is going one step further and offering an aggressive promotion to encourage Rinnai PROs and installers to try the Demand Duo R-Series, earning them a $150 rebate through June 30, 2021.”

Rinnai’s R-Series originated from the Demand Duo product portfolio; the first commercial hybrid water heating product introduced by Rinnai in 2015. It was developed to compete against high-efficiency tank-type water heaters in emergency replacement situations. Due to water heating inside traditional tanks, those products are put through a higher amount of strain, and that constant heating is what ultimately causes the tank to fail, leading to costly replacements. The Demand Duo was designed to solve this problem, by putting less stress on the tank through water being heated outside the tank in the Demand Duo’s tankless unit. With this solution comes a longer product service life, a longer warranty and more economical repairs.

To continue providing solutions to end users and contractors, Rinnai expanded the product category which now includes multiple tank sizes and Btu inputs including two tankless units mounted to a 119-gallon tank, known as the Demand Duo H-Series, a condensing hybrid water heater.

“Once contractors use the Demand Duo series, they seldom go back to installing tank-type water heaters because they can offer a product that is at the same price point but offers so many more advantages,” said Schmitz. “These advantages end up benefiting both the contractor and customer, while providing reliable performance whenever hot water is needed.”
