New Primary home - radiant flooring?

[Christen G.]

Hi folks,
I'm buying a new primary home and the floors are trashed. So yay! New Floors! 
We're dabbing with the idea of radiant heating and I had a few questions for those of you who have them or have installed them recently.

- Approx. how much should I budget?
- Electric vs. hydronic? Seems to me I wouldn't want water under my floors, but....?
- Do they work better with certain types of material (poured concrete, tile, engineered hardwood are currently on the table)
- Will they fully replace the HVAC/Heat pump that's there now? It's super old and will need to go in the next 3-5 years.
- I've read a fair amount about them, but I'd love to know any tips/tricks or suggestions that you have that otherwise isn't google-able?

The section I'm replacing is approx. 950-sqft - in Western Washington.
Thank you. Happy holidays,
