First we are not clear that what other operation there on submit button, is it a server side control or just html input??
assuming that your submit button is a html submit button, will call a javascript function to go to home page like this:
<script type="text/javascript">
function NavigateToHome() {
location.href = "Home.aspx";
}
</script>
<input type="submit" id="btnSave" value="Submit!!!" onclick="NavigateToHome();" />
