I am buying a house with 100amp service and the home inspecter said I would need at least 150 amp panel to service the hot tub that comes with the home. However, the hot tub is hooked up to the 100amp service panel and the hot tub works fine. Am I really running into any issues here if I do nothing? The seller will not install 150 amp service because he feels he doesn't have to. If I need to do something, I want to know how much I should ask at closing to fix. Please advise. Thanks
