    Would a Bosch Inverter Based Heat Pump need Backup Electric Heat Strips in NC

    Just curious.. Does anyone know if the Bosch Inverter based heat pump would work well enough in cooler temps that it could function WITHOUT the aid of back-up heating strips?

    ALL Heat pumps should have some type of Back Up!

    Depending on where you live and how low the temperature gets you may not need it in say Florida. But you should have it anyway as a back up heat source and if/when the heat pump goes into defrost. Unless you don't mind a blast of cold air every now & then.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    I suppose when the unit is down for repairs for who knows how long due to those specialized parts, what’s your heat source going to be?

    If you're inquiring if the heat pump could produce enough heat for your house without back up heat, the answer would be to first do a Manual J heat loss calculation to see how many btus are needed. Then a Manual S which looks at the performance data of the proposed heat pump to see if it can meet the load.

    Most likely not, but even if it could, you'd want the back up to provide emergency heat.
