## Questions & Answers

**Q: Will this mix with other transfer liquids ?**
A: I would get in touch with the manufacturer and ask them first, I know some solar thermal heat transfer products are incompatible. I think the E100 is mono ethylene glycol MEG but check first!

**Q: Can we use this in electric radiators?**
A: No. This product is for solar panels not for electric heaters.

**Q: Can this be used with a wet underfloor heating system?**
A: No, this is for solar heating system, underfloor heating is the same as radiators - water with inhibitor

**Q: Can you recommend a compatible pump to use with this solution?**
A: you need a magnetic drive 12 or 24 volt solar pump if you are using it for solar. Either way a magnetic drive pump is what you need for chemicals.
