Q:How do you order the decorative face plates?
by|Dec 1, 2022
1 Answer
Answer This Question

A:  Myson does not offer what I would call a decorative face plate for its kick space heaters. The units come with a black face plate. Myson does sell that same face plate in white, brushed stainless steel and chrome. The optional face plates are not sold on line but can be ordered through a Home Depot store. Chris 978 651 3301

    Q:Can unit be installed using PEX? If yes, maximum number of 90 degree angles to use
    by|Oct 2, 2021
    1 Answer
    Answer This Question

    A:  First PEX is not all the same. You never use potable water PEX on a hydronic heating system. It lacks an oxygen barrier to keep oxygen from defusing through the wall of the tube and into the closed loop heating system. This oxygen will destroy the ferrous metals in the heating system. Closed loop heating systems use the same water over and over again; hopefully for years. Therefore the oxygen in the water when the system is filled is quickly depleted and the ferrous metals never rust and the system never becomes air bound. Therefore if you are considering using PEX in a hydronic heating system you must use specific "Heat PEX" This is a special category of PEX pipe manufactured by a number of companies. It contains an oxygen barrier and is designed to be used in closed loop heating systems. There are those that say oxygen diffusion is a myth. They are wrong, very wrong. I know of many systems where plumbers used water PEX to save a little money only to leave customers with years of problems as the air destroyed the system from within. As to elbows, use as many as you want. The question assumes that the elbows are creating pressure drop and need to be accounted for. That is not the case. In a hyrdronic system it is the internal system pressure that is lifting the water. Two point three feet vertically for every one psi of system pressure. The circulator is not fighting gravity it is only creating a pressure drop sufficient to create flow. The co-efficient of drag created by the wall of the pipe and or the fittings is not something that needs to be accounted for. I understand why you intuitively ask the question but not to worry it is not something that needs to be accounted for. Chris 978 651 3301

      Q:I have tired everything in the installation booklet for trouble shooting, unit will only turn on when I am bleeding the unit. Once I tighten the screw the unit turns off. I have my water temp set to 200 degrees, yet will not turn on unless I loosen screw
      by|Oct 2, 2021
      1 Answer
      Answer This Question

      A:  You are either air bound or have piped the zone incorrectly. When you bleed the unit you are forcing hot water to the unit so it comes on. But when you stop bleeding the unit goes off because the water is cooled off by the fan. If you had flow there would be replacement hot water to keep the switch on and the blower running. But there is not so the heat sensing switch opens and the unit shuts off. The unit is fine you as demonstrated by the fact that the blower comes on when you force hot water to the unit by opening the bleeder. The question is why are you not getting flow. There are two common reasons for this. First you are air bound. There is an air bubble somewhere in the zone that is compressing the pumps force and preventing water form circulating. Circulators only move fluids, they will never compress a gas. To correct this you would purge the zone at the boiler, then fine tune using the bleeder. The second common reason is a piping error. Typically kick space heaters are piped in 1/2" off of a 3/4" or larger zone. You don't simply use 3/4 x 1/2 tees to create the 1/2" kick space heater sub zone. Water will not know you want some of it go down this 1/2" detour. Water moves to pressure drop so it will take the path of least resistance and bypass the 1/2" sub loop. There for you use 3/4x1/2 mono flow, scoop or venturey, Tees. These fittings have internal contours that artificially create pressure drop, so that the proper ratio of flow goes straight and the proper amount goes through the kick space heater. Now I don't want to wax on without more information. So if you have more questions or want to talk more about your specific situation feel free to give me a call. Chris 978 651 3301

        Q:Is the unit equipped with a temp sensor to turn the fan on and off, or is it controlled manually via the on/off switch? I ask because one of the reviews stated that they have to operate the fan via the switch on the face plate. Perhaps they are not using the unit properly, but i wanted to confirm before purchasing.

        Answer This Question

        A:  The unit is temperature controlled. Comes on when the water is like 170 degrees, goes off when then water cools down. It does have a "cooling" (snowflake) setting on the fan switch, maybe to just recirculate cool air on the floor back into the room during non-winter months. Otherwise in the heat position it is temp controlled. I replaced my old unit that was 23 years old since we're doing a bath remodel. I plan to replace the one in the kitchen (someday) with the same model. Good quality.

        by|Dec 5, 2020

          A:  It’s automatic with two speeds. It is activated when the heat comes on for the zone and the hot water flows thru the system.

          by|Mar 6, 2021

          A:  Inside any hydronic kick space heater is a devise called an aquastat. It is a fancy name for a thermostat that measures water temperate. When the aquastat senses the presence of hot water in the coil it allows current to flow to the blower motor. When the room thermostat is satisfied, it will shut off the pump that is moving the hot water through the coil. When the aquastat senses the coil is no longer hot it will open and stop the flow of current to the blower motor.

              We bought this heater for our remodeled kitchen which had previously depended on a small radiant heat source off the kitchen and was inadequate. I did a lot of research on kickspace heaters and thought this unit was the best for the money. We have been very pleased with the result. A huge advantage in my mind is the fact that this unit plugs in to a receptacle. Most other units have to be hard wired. The EZ Connect Kit is a bit pricey (you could most likely order all the parts individually for about 2/3rds the cost) but it does make installation simpler. If you are going to tie into an existing radiant water line make sure you get a pair of monoflow tees set at least 12 inches apart. We are going to install another unit in my daughter's house soon.

                It really kicks out the heat but I have to leave the fan on for that. I should have bought the one with a thermostat. That way it turns on when it is called for. Not looking forward to bending down each night to turn off and mornings visa versa.
