How To Install An Indirect Water Heater On A Boiler

Did you know an indirect water heater is one of the most cost effective ways to heat water? It eliminates the tremendous flue losses associated with gas-fired storage water heaters without the hassles and extra costs of tankless gas water heaters. When used with a modern, high-efficiency boiler these energy savings hold true even in the summer when your boiler isn't needed for heat!

The SuperStor Ultra is a high performance indirect water heater that can generate over 50% more hot water than many water heaters of a similar size. It has minimal heat loss, thanks to a 2" thick environmentally safe water blown foam insulation.

In the video below, Richard Trethewey, from Ask This Old House, explains the benefits of upgrading a tankless coil boiler to an indirect fired water heater. This projects features a SuperStor Ultra indirect water heater from HTP and a 007e circulator high efficiency circulator from Taco Comfort Solutions.

SuperStor Pro Pool Heater

The SuperStor Pro Pool from HTP is a stainless steel water heater that draws energy from a boiler to maintain a desired pool temperature. The hot boiler water flows through an internal heat exchanger in the tank, heating the pool water. The boiler must have an adequate BTU capacity and a circulator to transfer the BTUs to the pool heater. An optional control is available to monitor the pool water temperature.

The SuperStor Pro Pool water heater is made with 316L stainless steel tank construction to resist corrosion and last longer. It also eliminates the need for anode rods. Traditional coated tanks require anode rods to delay inevitable corrosion and tank failure. The SuperStor Pro Pool stainless steel will outlast any coated steel tank in the market. With 316L stainless steel construction, maintenance costs are virtually non-existent.

The SuperStor Pro Pool has thick water blown foam insulation allowing for minimal heat loss and low standby losses. The SuperStor Pro Pool can be linked to a boiler using either a zone valve or a circulated pump. The boiler used in conjunction with the pool heater must be appropriately sized to handle to pool volume.

It is ideally suited for high-rise condos, apartments and townhomes, fitting in bulkheads and drop down ceilings. Their small size makes for an easy installation in tight spaces.

The new Metro 120 ERV/HRV provides factory-set balancing suitable in most typical installation settings! A balance of +/-10% between supply and exhaust air flows is easily and automatically maintained for static pressures that differ by 0.2wc or less between an external static range of 0.3wc to 0.8wc.

The METRO Series has been designed with a removable motor and electronic panel for easy maintenance and repairs, plus a swing open ebox cover for quick access to circuit board and dip switches. Also available are optional white metal ceiling access panels in 3 sizes for easy servicing.

Our METRO HRVs (METRO 120F & METRO 120D) feature the patented aluminum HEX core, which carries a lifetime warranty, recirculating damper or fan defrost versions available, and offers multi-direction drain connections.

The METRO 120ERV offers a highly efficient fresh air ventilation solution that helps manage excess moisture and maximizes energy recovery during both heating and cooling seasons. The METRO 120 ERV also does not require a drain connection.

Magnetic Filter Installation: Prolonging Boiler and Component Life

By Jeff Waldman
Waldman Plumbing & Heating
12 Essex St. Lynn, MA 01902

Fernox TF1 Magnetic Filter

This is a photo of a Fernox TF1 magnetic filter 4 weeks after installation of a brand new Viessmann CU3A boiler with copper baseboard radiation. The streak marks on the filter body show the filter was leaking from being loaded with debris it had removed from the system.

Magnetic Filter Disassembled

This photo shows the magnetite, sludge and debris that adhered to the magnet inside the TF1 filter. This is only a small portion of what was removed from the system, the rest remained inside the filter body. This is only 4 weeks after a new boiler installation. This sludge was not new- it was existing from the old system inside all of the radiators and piping.


You can see the thickness of the magnetite and sludge here- the width of the magnet is visible at the bottom of the photo. Without this magnetic filter, this sludge and debris would stay in the system forever and wreak havoc on all of the boiler components-especially the ferrous components (piping, valves, circulators). This sludge is good job security for heating technicians- it ensures we will have to be back often to replace leaking components on the system.

Water Quality

This bucket shows the water and sludge that was removed from the filter body alone. Again, this is after only 4 weeks of a brand new system. Imagine what the water quality is like after 1, 2 or 5 years. The filter is easily cleaned and serviced. We also treated this water with a special cleaner and protectant after this visit to start off with clean water. The protectant will stop the water from getting to this point in the first place.
