Heater advice

[Nlangley]

Adding a heater for our R20. Thinking we’re going with Heatercraft 200 series with the “pro package”option.
Is the cir pump necessary? 
Is there anything else I need besides what comes included in this package? Any recommendations or changes I should consider? Thanks in advance

I think the rule is over 15 total feet of heater hose requires a circulation pump. I installed the heater in my last boat. I put the heater core in the helm locker behind the bow cushions, then ran the air ducts to the factory locations on an RZX3. I mounted the circulation pump on the port stinger just behind the motor and ran the heater hoses following the steering cable. The hardest part for me was using a hole saw (3" if I remember right) to cut through the fiberglass for the ducts. I thought it would cut easy, but turned into a pain.

Also, Raptor motors in some situations use two fuel pumps so there is an extra fuel pump relay on the fuse block on top of the motor. Very simple to wire your circulation pump to that extra relay so the pump is running anytime your engine is running.

I would add the circulation pump. Because the heater in the raptor runs off the coolant in the engine I find the heater temps really drop when you are idling. If you have the touch screen make sure you go into dealer settings and add the heater in rather than just using the heatercraft switch.

Maradyne makes a better product in my opinion. Whatever you do...do order direct from Heatercraft

Can't edit....but if you have a Raptor and are under warranty I would not do the install without a circ pump

Absolutely use the circulation pump. My RZR becomes so hot I have to move it away both at speed and idle. I’ve been in many other boats that are luke warm at best at speed and blows cool at idle. My pump is mounted vertically behind the starboard seat. Think of it this way, both the in and out lines tee off the coolant system fairly close together. It’s easier for the hot coolant to flow past the tees following the path of least resistance. You need the pump to draw the hot coolant into the heater system.
